Abstract:
Objective:To explore the application and effect of ambulatory electrocardiography in the detecting the long RR interval .Methods:The patients who took ambulatory electrocardiography with effective records of 20 to 24 hours in Zhongshan Hospital ,Fudan University from Jan 2012 to Mar 2013 were enrolled .The number of cases with RR interval ≥ 2 s were counted .The degree distribution of the longest RR interval and the types of arrhythmia that cause the longest RR interval were analyzed .Results:Among the 15 492 patients who underwent ambulatory electrocardiography with effective records of 20‐24 h , there were 1745 cases with long RR interval ≥2 s .The incidence rate of the long RR interval was 11 .26% .The average age of patients with long RR interval was older than that of general population .The incidence rate of long RR interval in male was higher than that in female .The degree distribution of the longest RR interval was from 2 s to 16 .85 s ,of which the most common ranged from 2 s to 3 s and contributed 83 .27% .There was 0 .23% cases over 10 s .The arrhythmia that caused the longest RR interval were , in order , persistent atrial fibrillation or atrial flutter , sinus arrest , ectopic P’ wave without conduction to ventricle and degree II type I atrioventricular block .Conclusions:Ambulatory electrocardiography is an simple , convenient and effective method for detecting long RR interval .It is conductive to detect the presence of bradyarrhythmia in time and take corresponding treatment .
