目的对心房颤动(Af)合并长R-R间期的动态心电图进行分析,从而进一步探讨房颤合并Ⅱ度房室传导阻滞(AVB)的诊断指标。方法对无锡市中医医院35例持续性房颤患者进行动态心电图检查,连续记录24 h。结果在睡眠状态下心室率缓慢时房颤患者易出现长R-R间期。结论心房颤动伴长R-R间期多为生理性,必须结合患者的原发病,结合发生的频度,长间期越多,越恒定,整个心室率偏慢,再除外迷走神经作用,才能做出心房颤动合并Ⅱ度房室传导阻滞的诊断。
Objective To analyze the dynamic electrocardiogram of atrial fibrillation (Af) combined with long R-R interval to further explore the diagnostic criteria of atrial fibrillation with second degree atrioventricular block (AVB). Methods A total of 35 patients with persistent atrial fibrillation in Wuxi TCM Hospital were examined by dynamic electrocardiogram for 24 hours. Results In patients with atrial fibrillation, prolonged R-R interval was found in patients with slow ventricular rate during sleep. Conclusions Atrial fibrillation with long RR interval is mostly physiological and must be combined with the patient’s primary disease, combined with the frequency of occurrence, the longer the period, the more constant, the entire ventricular rate is slow, except for vagal nerve function, to make Diagnosis of Atrial Fibrillation with Secondary Atrioventricular Block.
