Atrial fibrillation, also known as Afib, is an irregular, fast heartbeat that may cause symptoms like heart palpitations, fatigue, and shortness of breath. At least 2.7 million Americans are living with Afib. What Happens During Afib? Normally, your heart contracts and relaxes to a regular beat. In atrial fibrillation, the upper chambers of the heart (the atria) beat irregularly (quiver). Because of this irregular beat, a blood clot can form. If the blood clot breaks and enters the bloodstream, it could go to the brain and cause a stroke. About 15-20% of people who have strokes have this irregular heart rhythm. Patients with this condition are put on blood thinners to prevent strokes. Afib is a serious condition. If atrial fibrillation is not treated, it doubles the risk of heart-related death and increases the risk of having a stroke by five times. 2 AFIB Patient Guide-REV-PRINT.indd 2 5/31/19 2:54 PM Taking Control of Atrial Fibrillation Cause of Atrial Fibrillation Causes of Afib can be put into two categories; factors that Sometimes, you can control and factors you can’t control. the causes of Afib can Afib Risk Factors be unclear and other times, people with normal hearts You Can Control may develop • High cholesterol Afib. • High blood pressure • Heart disease • Smoking • Excess weight Afib Risk Factors • Caffeine You Can’t Control • Alcohol abuse • Family history • Lack of exercise • Advancing age • Some medications • Heart diseases from birth • Sleep apnea HOW TO REDUCE RISKS? 1 2 3 Improve Treat atrial Know your risk & your overall fibrillation and take risk-lowering health related conditions meds if needed 3 AFIB Patient Guide-REV-PRINT.indd 3 5/31/19 2:54 PM Taking Control of Atrial Fibrillation Types of Atrial Fibrillation Paroxysmal Persistent Afib Afib Paroxysmal Afib – Afib that comes and goes. The episode may last for seconds, minutes, hours, or days before the heart returns to its normal rhythm. As the heart goes in and out of Afib, Atrial your heartbeat may change from slow to fast and back again in short Fibrillation periods of time. Persistent Afib – Afib that does not stop by itself. Medication or a procedure called cardioversion is used to help the heart return to normal rhythm. If no treatment is done, the heart will stay in atrial fibrillation. Permanent Afib – Afib that cannot be corrected. Medications and procedures are not able to return the heart to normal rhythm. You will be given treatment to Permanent control your heart rate and reduce the risk of stroke. Afib What Type of Afib Do I have? Symptoms of Atrial Fibrillation The symptoms of Afib are different for each person. Some people can tell as soon as Afib begins. Other people don’t have any symptoms. 1. Feeling over tired or lacking energy (most common) 2. Having a fast heartbeat 3. Being short of breath 4. Racing or pounding heart 5. Struggling with everyday exercises or activities 6. Feeling pain, pressure, tightness, or discomfort in your chest 7. Feeling dizzy or lightheaded 8. Fainting What are my Afib symptoms? 4 AFIB Patient Guide-REV-PRINT.indd 4 5/31/19 2:54 PM Taking Control of Atrial Fibrillation How is Atrial Fibrillation Diagnosed? There are quite a few tests done when someone has a fast or irregular heartbeat. Your doctor may order one or more of these tests. Electrocardiogram (ECG) – An ECG is a snapshot of your heart’s electrical activity. It is often performed in a doctor’s office. Stickers (electrodes) are attached to your chest, arms and legs. This test measures the rate and rhythm of your heart. Holter monitor – A Holter monitor is a transportable ECG. It is typically worn for 24 to 48 hours. Stickers (electrodes) are placed on your chest and are then connected to a small recording machine. It records the electrical activity of your heart for your doctor to review later. Mobile Cardiac Monitoring – A continuous event monitor that is like a Holter monitor but is worn for up to 30 days. It will trigger a recording when it feels an abnormal rhythm (arrhythmia). The results are automatically sent to your doctor, who uses this information to evaluate your symptoms and determine if they are caused by an abnormal heart rhythm. This type of monitor helps diagnose Afib in patients without symptoms or in patients who have Afib only occasionally. Implantable Loop Recorder – Implantable loop recorders (ILRs) continuously record the heart’s rate and rhythm. It is placed under the skin of the chest, and the battery lasts about three years. It transfers information about your heart’s rate and rhythm to your doctor. ILRs are most commonly used for patients who have an irregular heart rhythm occasionally. Electrocardiogram (ECG) Holter monitor Implantable Loop Recorder 5 AFIB Patient Guide-REV-PRINT.indd 5 5/31/19 2:54 PM Taking Control of Atrial Fibrillation Other Tests Your doctor may order other imaging tests. These tests can help your doctor choose the right treatment plan for you. Echocardiogram – An echocardiogram uses sound waves to take pictures of your heart. There are two types of echocardiograms: Transthoracic Echocardiogram (TTE) – This type of echocardiogram gives your doctor a picture of your beating heart. It is non-invasive, which means nothing goes inside your body. A technician spreads gel on your chest and then moves a device, called a transducer, across your chest. A video then shows the size of your heart and how well your heart and heart valves are working. Transesophageal Echocardiogram (TEE) – A transesophageal echocardiogram, or a TEE, shows a clearer picture of the top chambers of your heart. A probe, called a transducer, is inserted through your mouth and moved down your esophagus (the tube that connects your mouth to your stomach). You will be given medicine to help you relax, and spray is used to numb the back of your throat so you are comfortable during the procedure. This type of echocardiogram is used to get more detail about heart valves and to check for clots that may have formed in the heart. 6 AFIB Patient Guide-REV-PRINT.indd 6 5/31/19 2:54 PM Taking Control of Atrial Fibrillation Atrial Fibrillation and Stroke One of the most serious risks of Afib is the risk of stroke. Afib makes the top chamber of the heart quiver so blood does not flow normally. With the blood moving more slowly, it can form clots. If a clot that forms in the left top chamber of your heart breaks free, it can travel out to your body. If a blood clot travels to the brain, it can cause a stroke. Your doctor will ask you about your medical history to figure out if your Afib increases your risk of having a stroke. If you are at increased risk for stroke, blood thinners are used to reduce your risk. 1. Blood clot can form during atrial fibrillation 2. Blood clot travels 3.

You and your doctor will work together on a treatment plan. ü Cardioversion The goals of treatment for Afib are to: ü Catheter Ablation for Afib • Prevent stroke AV Nodal Ablation • Control heart rate ü • Return the heartbeat to a normal rhythm if being in ü Medication a normal rhythm makes you feel better or is needed to control your heart rates ü Lifestyle Changes • Reduce any triggers for Afib Cardioversion If you go into Afib, your doctor may suggest a procedure called cardioversion as a treatment option. The cardioversion procedure involves an electrical current, or shock, to the heart muscle to restore the normal rhythm. It is a same-day procedure that takes minutes. Large patches (electrodes) will be placed on your chest and back. You will then be given sedation through an IV line to make sure you are comfortable. A timed electrical shock will pass through these electrodes to return your heart rhythm to normal. 8 AFIB Patient Guide-REV-PRINT.indd 8 5/31/19 2:54 PM Taking Control of Atrial Fibrillation Catheter Ablation for Afib Catheter ablation is a procedure that can be used to lessen triggers for Afib. The goal of this procedure is to reduce how often your Afib episodes happen as well as to decrease your Afib symptoms.

  • Common Types of Supraventricular Tachycardia: Diagnosis and Management RANDALL A
    Common Types of Supraventricular Tachycardia: Diagnosis and Management RANDALL A. COLUCCI, DO, MPH, Ohio University College of Osteopathic Medicine, Athens, Ohio MITCHELL J. SILVER, DO, McConnell Heart Hospital, Columbus, Ohio JAY SHUBROOK, DO, Ohio University College of Osteopathic Medicine, Athens, Ohio The most common types of supraventricular tachycardia are caused by a reentry phenomenon producing acceler- ated heart rates. Symptoms may include palpitations (including possible pulsations in the neck), chest pain, fatigue, lightheadedness or dizziness, and dyspnea. It is unusual for supraventricular tachycardia to be caused by structurally abnormal hearts. Diagnosis is often delayed because of the misdiagnosis of anxiety or panic disorder. Patient history is important in uncovering the diagnosis, whereas the physical examination may or may not be helpful. A Holter moni- tor or an event recorder is usually needed to capture the arrhythmia and confirm a diagnosis. Treatment consists of short-term or as-needed pharmacotherapy using calcium channel or beta blockers when vagal maneuvers fail to halt or slow the rhythm. In those who require long-term pharmacotherapy, atrioventricular nodal blocking agents or class Ic or III antiarrhythmics can be used; however, these agents should generally be managed by a cardiologist. Catheter ablation is an option in patients with persistent or recurrent supraventricular tachycardia who are unable to tolerate long-term pharmacologic treatment.

  • Accuracy of the Single Cycle Length Method for Calculation of Aortic Effective Orifice Area in Irregular Heart Rhythms
    AORTIC STENOSIS Accuracy of the Single Cycle Length Method for Calculation of Aortic Effective Orifice Area in Irregular Heart Rhythms Kerry A. Esquitin, MD, Omar K. Khalique, MD, Qi Liu, MD, Susheel K. Kodali, MD, Leo Marcoff, MD, Tamim M. Nazif, MD, Isaac George, MD, Torsten P. Vahl, MD, Martin B. Leon, MD, and Rebecca T. Hahn, MD, New York, New York; and Morristown, New Jersey Introduction: In irregular heart rhythms, echocardiographic calculation of aortic effective orifice area (EOA) re- quires averaging measurements from multiple cardiac cycles. Whether a single cycle length method can be used to calculate aortic EOA in aortic stenosis with nonsinus rhythms is not known. Methods: Transthoracic echocardiograms of 100 patients with aortic stenosis and either atrial fibrillation (AF) or frequent ectopy (FE) were retrospectively reviewed. The aortic valve velocity time integral (VTIAV) and the left ven- tricular outflow tract VTI (VTILVOT) were measured by two methods: the standard method (averaging multiple beats) and the single cycle length method. The latter matches the R-R intervals for VTIAV and VTILVOT.Stroke volume, EOA, and Doppler velocity index were calculated by both methods in all patients. The single cycle length method was used for short and long R-R cycles in AF and for postectopic beats (long R-R cycles) in FE. Results: In AF, long R-R cycles resulted in larger stroke volumes (73 6 21 vs 63 6 18 mL; P # .0001) but no difference in EOA (0.84 6 0.27 vs 0.82 6 0.27 cm2; P = .11), whereas short R-R cycles resulted in smaller stroke volumes (55 6 18 vs 63 6 18 mL, P # .0001) but a larger EOA (0.86 6 0.28 vs 0.82 6 0.27 cm2; P = .01).

  • Atrial Fibrillation: Diagnosis and Treatment CECILIA GUTIERREZ, MD, and DANIEL G
    Atrial Fibrillation: Diagnosis and Treatment CECILIA GUTIERREZ, MD, and DANIEL G. BLANCHARD, MD, University of California, San Diego, La Jolla, California Atrial fibrillation is the most common cardiac arrhythmia. It impairs cardiac function and increases the risk of stroke. The incidence of atrial fibrillation increases with age. Key treatment issues include deciding when to restore normal sinus rhythm, when to control rate only, and how to prevent thromboembolism. Rate control is the preferred manage- ment option in most patients. Rhythm control is an option for patients in whom rate control cannot be achieved or who have persistent symptoms despite rate control. The current recommendation for strict rate control is a resting heart rate of less than 80 beats per minute. However, one study has shown that more lenient rate control of less than 110 beats per minute while at rest was not inferior to strict rate control in preventing cardiac death, heart failure, stroke, and life- threatening arrhythmias. Anticoagulation therapy is needed with rate control and rhythm control to prevent stroke. Warfarin is superior to aspirin and clopidogrel in preventing stroke despite its narrow therapeutic range and increased risk of bleeding. Tools that predict the risk of stroke (e.g., CHADS2) and the risk of bleeding (e.g., Outpatient Bleed- ing Risk Index) are helpful in making decisions about anticoagulation therapy. Surgical options for atrial fibrillation include disruption of abnormal conduction pathways in the atria, and obliteration of the left atrial appendage. Catheter ablation is an option for restoring normal sinus rhythm in patients with paroxysmal atrial fibrillation and normal left atrial size.

  • Atrial Fibrillation in Acute Myocardial Infarction
    Original Article Atrial Fibrillation in Acute Myocardial Infarction Radha Bhattarai1, Sergey Anatolevich Sayganov1 1Department of hospital therapy and cardiology Northwestern State Medical University, Vasilevsky Ostrov, Bolshoe Prospect 85, Saint-Petersburg, Russia. ABSTRACT Background and Aim: New-onset atrial fibrillation frequently complicates acute myocardial infarction. The incidence ranges from 6 - 21% “1”.We aim to determine the incidence of atrial fibrillation in the setting of acute myocardial infarction. Methods: This was a single center prospective study, conducted in the coronary care unit of Saint-Petersburg Pokrovskaya city hospital, Russia, during the period, June 2013 to June 2014. Sixty consecutive patients of acute myocardial infarction with atrial fibrillation were included in this study. Onset, duration, and mode of termination of atrial fibrillation, clinical factors associated with its presentation and its relation with patient outcome were evaluated. Results: Among the 60 patients 33 (55%) had inferior wall myocardial infarction and 27 (45%) patients had anterior wall myocardial infarction. In patients with inferior wall myocardial infarction the onset of atrial fibrillation occurred within 24 hours in 30 (91%) patients, after 24 hour in 3 (9%) patients. The episode lasted for less than 24 hours in 12 (36%), and more than 24 hours in 21 (64%) patients. In anterior wall myocardial infarction atrial fibrillation occurred within 24 hours in 2 (7%) patients, on the second day in 25 (93%). The episode lasted less than 24 hours in 3 (11%), 48 hours in (85%), 72 hours in 1 (4%) Citation patients. There was a significant difference in the Radha Bhattarai, Sergey Anatolevich Sayganov. onset and duration of atrial fibrillation in relation to Atrial Fibrillation in Acute Myocardial Infarction.

  • Premature Ventricular Contraction Increases the Risk of Heart Failure
    www.nature.com/scientificreports OPEN Premature ventricular contraction increases the risk of heart failure and ventricular tachyarrhythmia Yun Gi Kim1,3, Yun Young Choi1,3, Kyung‑Do Han2, Kyoung Jin Min1, Ha Young Choi1, Jaemin Shim1, Jong‑Il Choi1* & Young‑Hoon Kim1 Premature ventricular contraction (PVC), a common arrhythmia afecting 1–2% of the general population, has been considered to have a benign clinical course. However, people with PVC often develop heart failure and ventricular arrhythmias such as ventricular tachycardia. We aimed to clarify the risk of heart failure and lethal ventricular arrhythmias in people with PVC. The Korean National Health Insurance Service database was used for this study. People who underwent nationwide health check‑ups in 2009 were enrolled in this study and clinical follow‑up data until December 2018 were analyzed. Newly diagnosed PVC in 2009 (≥ 1 inpatient or outpatient claim) were identifed and cumulative incidence of heart failure (≥ 1 inpatient claim) and ventricular arrhythmias (≥ 1 inpatient or outpatient claim) were compared. A total of 4515 people were frst diagnosed with PVC in 2009 among 9,743,582 people without prior history of PVC, heart failure, or ventricular arrhythmias. People with newly diagnosed PVC in 2009 had a signifcantly higher incidence of heart failure compared to those without PVC [adjusted hazard ratio (HR) 1.371; 95% confdence interval (CI) 1.177–1.598; p < 0.001]. Signifcant interaction was observed between age and PVC with young age people at greater risk of developing heart failure for having PVC. The incidence of ventricular arrhythmia was also signifcantly increased in people with PVC (HR 5.588; 95% CI 4.553–6.859; p < 0.001).

  • Acute Management of Atrial Fibrillation: Part I. Rate and Rhythm Control DANA E
    COVER ARTICLE PRACTICAL THERAPEUTICS Acute Management of Atrial Fibrillation: Part I. Rate and Rhythm Control DANA E. KING, M.D., LORI M. DICKERSON, PHARM.D., and JONATHAN L. SACK, M.D. Medical University of South Carolina, Charleston, South Carolina Atrial fibrillation is the arrhythmia most commonly encountered in family practice. Serious complications can include congestive heart failure, myocardial infarction, and thromboembolism. Initial treatment is directed at controlling the ventricular rate, most often with a calcium channel blocker, a beta blocker, or digoxin. Medical or electrical cardioversion to restore sinus rhythm is the next step in patients who remain in atrial fibrillation. Heparin should be administered to hospitalized patients undergoing med- ical or electrical cardioversion. Anticoagulation with warfarin should be used for three weeks before elective cardioversion and continued for four weeks after cardioversion. The recommendations provided in this two-part article are consistent with guidelines published by the American Heart Association and the Agency for Healthcare Research and Quality.
