Abstract：Objective To investigate the characteristics of 24-hour ambulatory electrocardiogram in atrial fibrillation (Af)with long R-R interval.Methods The clinical data of 500 patients with Af with long R-R interval treated in Lianyungang Second People's Hospital from March 2020 to March 2022 were analyzed retrospectively.All patients underwent 24-hour ambulatory ECG.The occurrence time of Af with long R-R interval was counted.According to the occurrence time,they were divided into sleep related group (long R-R interval occurred from 21:00 to 6:00,319 cases) and non sleep related group(long R-R interval occurred during non sleep,181 cases).The ECG characteristics,escape rhythm Escape stroke and syncope.Results There were no significant differences in gender,age,NYHA grade,disease type and Af duration between sleep related group and non sleep related group (P＞0.05).The slowest ventricular rate,mean ventricular rate and fastest ventricular rate in sleep related group were higher than those in non sleep related group,with statistically significant differences (P＜0.05).The incidences of escape rhythm,escape and syncope in sleep related group were lower than those in non sleep related group,with statistically significant differences (P＜0.05).Conclusion 24 h ambulatory electrocardiogram can effectively detect the characteristics of Af with long R-R interval.Af with long R-R interval often occurs in sleep.We should pay close attention to the 24 h ECG examination of patients with Af with long R-R interval and take intervention measures in time.
