The authors used programmed pacing of the ventricles in a total of 55 subjects (41 men and 14 women). In a group of 36 patients with chronic relapsing ventricular tachycardias they assessed the sensitivity of this method as 83.3%. In 19 subjects without serious organic heart disease and without clinically confirmed tachyarrhythmias programmed pacing of the ventricles did not reveal diagnostic ventricular tachycardias. The specificity of the method was 100%. The highest detection rate of diagnostic ventricular tachycardias was obtained when four extrastimuli were applied during the sinus rhythm and 2-4 extrastimuli, using the basic stimulation rate of 100/min.
