The purpose of this article is to investigate the occurrence of symptomatic paroxysmal supraventricular tachycardia (PSVT) in untreated patients and to assess factors that influenced its occurrence. We studied 34 patients with this arrhythmia during an observation period in which they received no antiarrhythmic drug therapy for up to 90 days. Recurrence of PSVT was documented by telephone transmission of the electrocardiogram. Each patient was allowed to have exactly one episode of tachycardia before being removed from the study. We measured how long patients remained free of their tachycardia (the tachycardia-free period) and heart rate during tachycardia. Twenty-nine of the 34 patients had an attack of symptomatic tachycardia within the 90-day observation period. The proportion of patients who had not had any symptomatic PSVT by each day of follow-up was calculated using the Kaplan-Meier method as follows: 75% by day 3, 50% by day 19, 25% by day 36, and 17% by day 90. Patients with any other heart or lung disease had significantly shorter tachycardia-free periods. The mean heart rate during spontaneous tachycardia was 203.5 +/- 34.9 beats per minute (range, 142 to 288 beats per minute). Patients with longer tachycardia-free periods had significantly faster heart rates during tachycardia.
