一般,睡眠时室性心律失常减少。本文对1260例示有室性异位搏动的24小时动态心电图中,表现为睡眠时异位搏动明显增多的50例进行分析。并与50例年龄、性别和24小时室性异位搏动发生率近似的对照组进行比较。以便了解睡眠时加剧的室性心律失常的临床和心电图特点。研究组和对照组均为男性29例、女性21例。平均年龄男63.2±18.7岁,女64.4±16.4岁。睡眠时,研究组每小时室性异位搏动(平均43.2±30.7次)的发生率较对照组(62.9±16.3次)为高。(P<0.005)。白天,研究组每小时室性异位搏动(平均45.2±13.6次)的发生率较对照组(平均67.7±13.8次)为低(P<0.05)。复杂性室性心律失常,研究组病例睡眠时也显示明显增多(x~2=22.1;P<0.001),而对照组减少(x~2=19.1;P<0.001)。两组夜间心率均较白天为慢,而
In general, sleep reduction of ventricular arrhythmias. In this paper, 1260 cases showed ventricular ectopic beating in 24-hour ambulatory ECG, the performance of ectopic beats significantly increased sleep 50 cases were analyzed. And compared with 50 cases of age, gender and 24-hour incidence of ventricular ectopic beating compared to the control group. In order to understand the clinical and electrocardiographic features of ventricular arrhythmias exacerbated by sleep. The study group and the control group were 29 males and 21 females. The average age of male 63.2 ± 18.7 years old, female 64.4 ± 16.4 years old. Sleep, the study group hourly ventricular ectopic beats (average 43.2 ± 30.7 times) incidence of the control group (62.9 ± 16.3 times) is higher. (P <0.005). During the day, the incidence of ventricular ectopic beats per hour (average 45.2 ± 13.6) in the study group was lower than that in the control group (mean 67.7 ± 13.8) (P <0.05). Complicated ventricular arrhythmia was also observed in the study group at sleep (x 2 = 22.1; P <0.001), while in the control group decreased (x 2 = 19.1; P <0.001). Nighttime heart rate was slower than daytime in both groups
