title: [Isolated ventricular tachycardia without patent cardiopathy].
abstract: The authors have made a further study of the case notes of 49 patients who were followed up for several years with isolated ventricular tachycardia occurring in a heart which was otherwise healthy; such tachycardias are also called essential or idiopathic. First they define the criteria necessary for the diagnosis of essential ventricular tachycardia: -- an arbitrary age criterion (less than 45 years in men and 50 years in women) which seeks to exclude the so-called "arterial" ventricular tachycardias; -- a follow-up period of supervision of more than two years, which excludes certain primary cardiomyopathies whose presenting feature is a series of attacks of ventricular tachycardia. They then attempt to classify the ventricular tchycardias into four types, according to their clinical features and the electrocardiographic tracings at rest and on exercise, and to predict the prognosis. The most frequently encountered and benign type was the classical ventricular tachycardia of Bouveret.
