目的分析动态心电图心房颤动合并长R-R间期(>1.5s)、逸博及逸博心律对病理性房室传导阻滞的诊断价值和临床意义。方法将我科动态心电图记录长R-R间期(>1.5s)、逸博及逸博心律出现时间患者根据与睡眠的关系分为睡眠相关组(睡眠组)和非睡眠相关组(非睡眠组),对24h动态心电图进行详细记录和分析。结果组间全天最大平均心室率和最小平均心室率比较,P>0.05;夜间最小平均心室率和最长R-R间期均值比较,P<0.05;日间平均心室率、日间最大平均心室率、日间最小平均心室率、夜间平均心室率、夜间最大平均心室率、全天平均心室率和长R-R间期人均次数比较,P<0.01。结论对于心房颤动合并长R-R间期患者,明显出现的长R-R间期次数与睡眠无关,伴有不同程度的头晕、心悸、乏力或晕厥病史者,临床应高度怀疑病理性房室传导阻滞。
Objective To analyze the diagnostic value and clinical significance of ambulatory atrial fibrillation combined with long R-R interval (> 1.5 s) and Yi-Bo and Yabo heart rhythm for pathological atrioventricular block. Methods The subjects were divided into sleep-related group (sleep group) and non-sleep-related group (non-sleep group) according to the relationship with sleep during the long RR interval (> 1.5s) 24h Holter detailed recording and analysis. Results The maximal mean ventricular rate and minimum mean ventricular rate were compared between the two groups (P> 0.05). The average nighttime minimum ventricular rate and the longest RR interval mean were compared (P <0.05). The average daytime ventricular rate, maximum daytime mean ventricular rate , The average daily minimum ventricular rate, the average night ventricular rate, the maximum nighttime average ventricular rate, the average daily ventricular rate and long RR interval per capita, P <0.01. Conclusions For patients with atrial fibrillation and long R-R interval, the obvious number of long R-R intervals has nothing to do with sleep, accompanied by varying degrees of history of dizziness, palpitations, fatigue or syncope, the clinical should be highly suspected pathological atrioventricular block.
