Abstract
In a selected group of 10 apparently healthy subjects and 22 patients with organic heart disease, all with frequent ventricular ectopic beats on Holter monitoring, we assessed the influence of sympathetic activation by comparing the arrhythmogenic effects of a symptom-limited bicycle exercise stress test and 90° head up tilt. Tilting reduced ventricular arrhythmias in the normal subjects (-48±18% from 9±2 beats min -1, P-1, P
