Paroxysmal ventricular tachycardia

Repetitive paroxysmal ventricular tachycardia.

Case 1. A man, aged 22, was first seen as an out-patient in May, 1958. He complained of dyspnoea on strenuous exertion but was able to lead a normal active life for a man of his age. He had never been conscious of palpitation. His heart action was known to have been irregular since childhood but otherwise he had had no relevant illness; no previous electrocardiogram had been recorded. On clinic...

Paroxysmal Ventricular Tachycardia.

Paroxysmal ventricular tachycardia is comparatively rare. It was first differentiated from paroxysmal auricular tachycardia by MacKenzie (1908) through his study of simultaneous venous and arterial tracings. Others (Franck, 1894, and Hoffman, 1900) had hinted that this might be the case. The following year Lewis (1909) published the first electrocardiogram that supported this contention; the rh...

Paroxysmal Ventricular Tachycardia: A Study

A review is presented of 107 cases of paroxysmal ventricular tachycardia. In the majority it was associated with acute coronary thrombosis or coronary sclerosis, in some with rheumatic valvular disease, and in others with no organic heart disease. It is generally critical and demands careful attention. Occasional cases are overlooked because only one heart sound is present for each cardiac cycl...

Q fever presenting with paroxysmal ventricular tachycardia.

Repetitive paroxysmal ventricular tachycardia with fusion beats.

Paroxysmal ventricular tachycardia is unfortunately fairly common and is usually associated with serious heart disease and a poor prognosis. Of late, however, attention has been drawn by numerous observers to a rare and apparently benign form where paroxysms of ventricular tachycardia interrupted by normal sinus beats keep on recurring for months or years. In view of the apparent rarity of the ...
