    Media backgrounder Cardiac Arrhythmia and Catheter Ablation Technique Cardiac arrhythmia – when the heart falls out of rhythm Cardiac arrhythmias (CA) represent a group of conditions with an abnormal heart rhythm or heart rate. This may involve the heart beating too fast (over 100 bpm), too slow (less than 60 bpm) or irregularly.1 Arrhythmias are often caused by problems with the electrical system that regulates the steady heartbeat and can originate in the lower chambers of the heart (ventricles) or in the upper chambers (atria).2 There are various types of arrhythmia; the most common forms include atrial fibrillation (AF), atrial flutter and atrioventricular nodal re-entrant tachycardia. Noticeable warning symptoms include fluttering in the chest, shortness of breath, fatigue, chest pain, dizziness or fainting.3 Many people experience irregular heartbeats at some point in their lives. Most of the time they are harmless, especially when not associated with other heart conditions. However, some arrhythmias can be serious and even life-threatening if left untreated. For example, atrial fibrillation is the most common cardiac arrhythmia and an independent contributor to mortality, morbidity and impaired quality of life.4,5 According to data from the long-term, ongoing Framingham heart study, AF is associated with a 1.5- to 1.9-fold higher risk of death. This is in part attributed to the strong association between AF and thromboembolic events (where the blood in the heart can clot).6 Overall, AF is estimated to be responsible for approximately 15 percent of all strokes7,8,9 and 20 percent of all ischemic strokes.10 Cardiac arrhythmia – a growing global burden • Anyone can develop arrhythmias, even young adults without previous heart problems.

    Catheter Ablation for Supra-Ventricular Tachycardia Delivering the best in care UHB is a no smoking Trust To see all of our current patient information leafl ets please visit www.uhb.nhs.uk/patient-information-leafl ets.htm About this patient information leaflet This patient information leaflet The Heart is about supra-ventricular tachycardia, one of the main heart rhythm problems we treat with catheter ablation procedures. It is one of a series of leaflets that we have produced, written in everyday language that explains what a particular heart rhythm condition is, what its symptoms are, why it occurs and how it is treated. This booklet has been prepared for individuals preparing to undergo one of the procedures described or for individuals looking for more information about these procedures. The information provided within this booklet does not replace the consultation that takes place between the patient and the doctor. Supra-ventricular tachycardia What is supra-ventricular tachycardia? Supra-ventricular tachycardia (SVT) is a condition that results Supra-Ventricular Tachycardia in the heart beating faster than normal. The rapid heart rate produces a sensation of palpitations or fluttering in the chest. It is an abnormal heart rhythm. The heart has an electrical system that controls the rhythm and speed of the heartbeat. An SVT is caused by an extra electrical connection within the smaller, upper chambers of the heart (called atria). This extra connection allows the normal electrical system to run faster and out of control. These episodes or attacks of palpitations can last anywhere from minutes to hours. They are often unpredictable.

A total of 3,850 patients without a previous history of catheter ablation procedure were enrolled. We analyzed 2-year effectiveness of the index ablation. Any redo ablation, electrical car- dioversion, or use of antiarrhythmic drug beyond the blanking pe- riod of 3 months was considered a failure of index ablation. Results: Overall recurrence rate following AF ablation was 61.1%. The recurrence rate was lower in patients under 65 years old than in those over 65 years old (hazard ratio [HR] 0.89; 95% confidence interval [CI], 0.81 to 0.97, P=0.009).
