摘　　要：目的研究室性早搏后心率变化情况与疾病严重程度的相关性并探讨其临床应用价值。方法测定152例奎陛早搏患者奎陛早搏后窦性心率加速即震荡初始（TO）、窦性心率减速即震荡斜率（TS）以及心率是否相等。结果高血压、心肌炎及无器质性心脏病患者TO和／或鸭异常率较低，而冠状动脉粥样硬化性心脏病（冠心病）患者异常率较高，3者与冠心病患者比较差异有统计学意义（P〈0．05）；11例冠心病病情危重患者室性早搏后心率相等，余141例患者室性早搏后心率均不等。结论室性早搏后心率变化的测定对心脏疾病患者病情危重程度有一定的预测价值。Objective To analyze the correlation between heart rate variability and prognosis of heart diseases with occurrence of ventricular premature beat. Methods One hundred and fifty-two heart disease patients who suffered from ventricular premature heat were enrolled. Indexes of Turbulence Onset （TO） and Turbulence Slope（TS） was observed in this research. Meanwhile, the heart rates before and after ventricular premature beat were compared. Results In patients with hypertension, myocarditis, without heart diseases, the differences of TO and TS before and after ventricular premature beat were not significant. But in patients with coronany heart disease, the TO and TS were significant different. Conclusion Heart rate variability after onset of ventricular premature beat could be a predictor for prognosis of heart disease.
