Abstrakt: This study investigates the relation of spontaneous ventricular arrhythmia on ambulatory electrocardiographic (ECG) monitoring to the subsequent inducibility of ventricular tachycardia during programmed electrical stimulation. Eighty patients (65 men, 15 women), whose mean age was 58 years, presented with one of the following: sustained ventricular tachycardia (n = 54); sudden death requiring resuscitation (n = 4); ventricular fibrillation (n = 11); or syncope thought to be of cardiac origin (n = 11). All patients had 24 hour ambulatory electrocardiograms and programmed electrical stimulation while receiving no antiarrhythmic therapy. Programmed electrical stimulation resulted in inducible sustained ventricular tachycardia (defined as a rate of ≥120 beats/min for ≥1 minute or requiring intervention) in 53 of the 80 patients.
