摘　　要：目的探讨心肌梗死后性生活能否引起新的心肌缺血、损伤。方法首发心肌梗死男性患者32例作为研究对象,佩戴动态心电图进行性事试验及体力试验。检测两种试验心率变异性(HRV),定量分析正常窦性R-R间期的标准差(SDNN)、全程记录中每5minNN间期平均值的标准差(SDANNI)、相邻窦性R-R间期差值的均方根值(RMSSD)、低频(LF)及高频(HF)指标。结果检测HRV中SDNN、SDANNI、RMSSD、LF、HF,性事试验分别平均为95.3ms、76.5ms、18.3ms、738.5ms2、520.7ms2;体力试验分别平均为114.5ms、87.4ms、25.4ms、583.7ms2、548.5ms2,两组差异有统计学意义(P<0.01)。结论心肌梗死后进行性生活可诱发新的心肌缺血、损伤。HRV可定量分析迷走神经张力和交感神经兴奋性,有助于对心肌梗死后性生活安全性进行指导。Objective To investigate whether sexual activity after myocardial infarction can trigger a new myocardial ischemia or injury.Methods A total of 32 men experiencing first myocardial infarction were examined.All subjects wore a Holter ECG during both sexual activity and physical exercise.Heart rate variability （HRV） and SDNN,SDANNI, RMSSD,LF,HF were quantitatively analyzed.Results The index of SDNN,SDANNI,RMSSD,LF,HF were 95.3 ms, 76.5 ms,18.3 ms,738.5 ms2,520.7 ms2 respectively during sexual activity; and 114.5 ms,87.4 ms,25.4 ms,583.7 ms2,548.5 ms2 respectively during physical exercise.The differences were significant （P0.01） .Conclusion Sexual activity might induce myocardial ischemia/injury or arrhythmia.Quantitative analysis of HRV can reflect vagal tone and sympathetic nerve activity,and therefore,it may guide safe sexual activity after myocardial infarction.
