Transtelephonic ECG monitoring over a median of 357 days detected atrial fibrillation in 18% (3 of 17) of patients with AVNRT, an incidence higher than expected for the general population.
Observational (n=17)
The incidence of atrial fibrillation in patients with AVNRT is 18%, which is higher than expected for the general population.
The occurrence of atrial fibrillation in patients with paroxysmal supraventricular tachycardia (PSVT) has been well documented when PSVT is secondary to atrioventricular reentry, but not when PSVT is secondary to atrioventricular nodal reentry (AVNRT). Seventeen patients with AVNRT were followed using transtelephonic electrocardiogram monitoring to document symptomatic tachycardias. The median length of telephone monitor surveillance was 357 days. Fifteen of 17 patients transmitted electrocardiograms that showed PSVT. Three of 17 patients (18%) transmitted electrocardiograms that showed atrial fibrillation. A transition from PSVT into atrial fibrillation was not recorded, but all three did have PSVT recorded on other days of follow-up. We report the occurrence of atrial fibrillation in patients with AVNRT and that its incidence is higher than expected for the general population.
Hurwitz et al. (1990) conducted an observational in Paroxysmal supraventricular tachycardia due to atrioventricular nodal reentry (AVNRT) (n=17). Transtelephonic electrocardiogram monitoring was evaluated on Occurrence of atrial fibrillation. Transtelephonic ECG monitoring over a median of 357 days detected atrial fibrillation in 18% (3 of 17) of patients with AVNRT, an incidence higher than expected for the general population.
