Abstract
Heart rate variability on 24-hour electrocardiographic recording was a ssessed in 23 patients without structural heart disease before and aft er 2 months of oral treatment with verapamil prescribed for paroxysmal atrioventricular nodal reentrant tachycardia, Verapamil had no signif icant effect on overall heart rate variability in the frequency domain , but it increased ultra low frequency power and decreased the low-fre quency/high-frequency ratio, deemed to be a marker of sympathetic acti vity.
