Although the concept of J wave syndromes is widely used and accepted, there has been tremendous debate over the definition of J wave, its ionic and cellular basis and arrhythmogenic mechanism. In this review article, we attempted to discuss the history from which the concept of J wave syndromes (JWS) is evolved and current controversies in JWS.

Received September 15, 1953 Among the large number of patients suffering from syncopal attacks who attended the National Heart Hospital during a four-year period, there were four in whom examination revealed sinus bradycardia alternating with prolonged phases of auricular tachycardia. These patients presented a difficult problem in treatment. Each required at least one admission to hospital and in one case the symptoms were so intractable as to necessitate six admissions in five years. Two patients had mitral valve disease, one of them with left bundle branch block. One had aortic valve sclerosis while the fourth had no evidence of heart disease. THE HEART RATE The sinus rate usually lay between 30 and 50 a minute, a rate as slow as 22 a minute being observed in one patient (Table I).

  • What Is an Arrhythmia?
    ANSWERS Cardiovascular Conditions by heart What is an Arrhythmia? An arrhythmia is an abnormal heart rhythm. ECG strip showing a normal heartbeat It may feel like fluttering or a brief pause. It may be so brief that it doesn’t change your overall heart rate (the number of times per minute that your heart beats). Or it can cause the heart rate to be too slow or too fast. Some arrhythmias don’t cause any symptoms. Others ECG strip showing bradycardia can make you feel lightheaded or dizzy. There are two basic kinds of arrhythmias. Bradycardia is when the heart rate is too slow — less than 60 beats per minute. Tachycardia is when the heart rate is too fast — more than 100 beats per minute. ECG strip showing tachycardia What are the signs of arrhythmia? How are arrhythmias treated? • When it’s very brief, an arrhythmia can have almost Before treatment, it’s important for your doctor to no symptoms. It can feel like a skipped heartbeat know where an arrhythmia starts in the heart and that you barely notice. whether it’s abnormal. An electrocardiogram (ECG or • It also may feel like a fluttering in the chest or neck. EKG) is often used to diagnose arrhythmias. It creates a graphic record of the heart’s electrical impulses. • When arrhythmias are severe or last long enough to Using a Holter monitor, exercise stress tests, tilt table affect how well the heart works, the heart may not test and electrophysiologic studies (“mapping” the be able to pump enough blood to the body.

Shaw From the Cardiac Department, Royal Devon and Exeter Hospital, Exeter, Devon This paper presents thefeatures of 46 patients with unexplained bradycardia. Patients were ad- mitted to the study if their resting atrial rate was below 56 a minute on two consecutive occasions. Previous electrocardiograms and the response to exercise, atropine, and isoprenaline were studied. The ages of thepatients variedfrom I3 to 88years. Only 8 had a past history ofcardiovascular disease other than bradycardia, but 36 hJd syncopal or dizzy attacks. Of the 46 patients, 35 had another arrhythmia in addition to bradycardia; at some stage, i6 had sinus arrest, i.5 hadjunc- tional rhythm, 12 had fast atrial arrhythmia, I6 had frequent extrasystoles, and 6 had atrio- ventricular block. None had the classical features of sinoatrial block. Arrhythmias were often produced by exercise, atropine, or isoprenaline. Drug treatment was rarely satisfactory, but only i patient needed a permanent pacemaker. It is suggested that the majority of the patients were suffering from a pathological form of sinus bradycardia. The aetiology remains unproven, but the most likely explanation is a loss of the inherent rhythmicity of the sinoatrial node due to a primary degenerative disease. The descriptive title of 'the lazy sinus syndrome' is suggested. copyright.
