title: Pathophysiology of ventricular tachycardia in man.
abstract: Programmed electrical stimulation of the heart as a method to study mechanisms of arrthythmias is discussed in patients with ventricular tachycardia. Chronic recurrent ventricular tachycardia seems to be based on a reentry mechanism. Observations in patients with ventricular tachycardia during the first 24 hours after myocardial infarction suggest a focal origin of the arrhythmia.
