本文收集了资料完整的住院老年性心脏病引起的室性早搏122例,根据临床诊断结合心电图,从室早发生的原因、原理、定位、室早QRS-T波群的形态、早搏指数(PI)、室早后第一个心动周期T波的变化等,与对照组进行了比较分析,结果显示:除PI外,其他两组P<0.01,有显著的差异性。 In this paper, 122 cases of premature ventricular contractions caused by hospitalized senile heart disease were collected. Based on the clinical diagnosis and electrocardiogram, the causes, principles, location, the morphology of early QRS-T wave group, the premature beat index ), And the changes of the first cardiac cycle T wave in the early and later period of the heart were compared with those in the control group.
