Abstract
Objective To analyze the relationship between atrial fibrillation complicating long R-R interval, escape beat and escape heart rhythm and pathological atrioventricular block by dynamic electrocardiography (DCG). Methods 126 patients with atrial fibrillation were divided into group A (being related to sleep) and group B (being not related to sleep) according to the factor whether long R-R interval, escape beat and escape heart rhythm relevant to sleep. All were detected by DCG for 24 hours. Results The cases with1.5～2.0 s long R-R interval, more than 2.0s long R-R interval, escape beat and escape heart rhythm were (26.02±6.03), (7.39±1.05 ) and (6.90±1.28)in group A and (203.05±41.01), (35.48±7.52), (28.10±6.25) in group B respectively. The cases of group B were markedly more than those in group A. Conclusion Those atrial fibrillation complicating long R-R interval, escape bbeat and escape heart rhythm were related to sleep could not be deemed as pathological atrioventricular block, while those were not related to sleep could be considered pathological atrioventricular block.关键词
