[Significance and prognosis of ventricular extrasystole induced by exertion in patients with arterial hypertension with a normal electrocardiogram].

We studied 13 patients with systemic arterial hypertension and normal electrocardiograms so as to evaluate the significance and prognosis of frequent and complex ventricular premature beats (VPB) induced by exercise testing. After a period of 9 to 33 months of follow-up (mean = 17.6 months), we repeated the exercise testing with the same protocol in all cases. In nine patients (69.2%), the arrhythmia disappeared during exercise, two increased the number of VPB and two others reduced the number of the arrhythmia. Complications, such as sustained ventricular tachycardia, were not seen in any case. The appearance of frequent and complex VPB with stress testing does not seem enhance the risk of sudden death or episodes of spontaneous ventricular tachycardia in patients with arterial hypertension but without electrocardiographic signs of cardiac hypertrophy.
