title: [Incidence of atrial fibrillation in paced patients with complete atrioventricular block].
abstract: The aim of the study was to evaluate the incidence of chronic AF in patients paced due to complete AV block. The study group consisted of 130 pts (70 F, 60 M), mean age 68.6 +/- 14.3 y in whom pacemakers were implanted in the years 1990-1998 due to III degree AV block. There were 76 pts with VVI, 24 DDD and 30 VDD modes of pacing. Follow-up period was mean. 47.6 +/- 25.9 m (7-110). Chronic AF developed in 25 pts (19.2%). In the VVI group the incidence of AF was significantly higher than in DDD and VDD groups--30.3% vs. 4.17% and 3.33% respectively, p < 0.01. Ventriculo-atrial conduction (VAC) was found in 19 pts (14.6%), but did not correlate with the development of AF. Stroke occurred in 2 pts with VVI pacing and chronic AF. In conclusion, in pts with complete AV block VDD and DDD pacing significantly reduce the incidence of chronic AF as compared to VVI.
