摘　　要：目的探讨冠心病伴缺血性J波患者窦性心律震荡现象(heart rate turbulence,HRT)的临床意义。方法选择2008～2011年于我院进行24小时动态心电图检查患者120例,其中冠心病伴缺血性J波者、冠心病非缺血性J波者及无器质性心脏病者各40例,均检出有室性早搏,计算窦性心律震荡初始(TO)及窦性心律震荡斜率(TS)等指标。结果冠心病伴缺血性J波组TO较无器质性心脏病组高(P<0.05),TS较无器质性心脏病组低(P<0.05);与冠心病非缺血性J波组比较,TO及TS也有统计学意义(P<0.05)。结论冠心病发生缺血性J波时窦性心律震荡现象减弱,更易发生猝死。Objective To study clinical significance of sinus rhythm turbulence with ischemic J wave in patients with coronary heart disease. Methods One hundred and twenty patients were chosen. The patients were checked by 24 hour dynamic electrocardio- gram during the period from 2008 to 2011 in our hospital. The patients were divided into 3 groups：coronary heart disease complicated with ischemic J wave （N = 40） ,coronary heart disease without ischemic J wave （N = 40） and non organic heart disease （N = 40）. Vcntricular extrasystoles were detected in all the cases. The turbulance onset （TO） index and turbulance slope （TS） index were com- pared among groups. Results The TO index in group of coronary heart disease with ischemic J wave were higher while TS index lower than that in other two groups （ P 〈 0.05 ）. Conclusions Sinus rhythm turbulence is weaken when coronary heart disease with isehemic J wave. These patients may be more susceptible to sudden death.
