目的回顾性分析窦性心律震荡现象对急性冠状动脉综合征的影响。方法对137例急性冠状动脉综合征患者(包括不稳定型心绞痛39例,急性心肌梗死98例),发病后的动态心电图进行分析,测量窦性心律震荡参数,震荡初始(TO)与震荡斜率(TS)值,观察TO、TS变化对急性冠状动脉患者预后的影响。结果患者随访(21.0±11.0)月,共死亡16例。窦性心律震荡减弱程度与低左心室射血分数、年龄与急性冠状动脉综合征的发展变化显著相关。结论窦性心律震荡现象可作为反映急性冠状动脉综合征预后及心功能预测的参考指标。
Objective To retrospectively analyze the effect of sinus rhythm concussion on acute coronary syndrome. Methods 137 patients with acute coronary syndrome (including 39 cases of unstable angina and 98 cases of acute myocardial infarction) and dynamic electrocardiogram after onset were analyzed to measure the parameters of sinus rhythm, initial onset of oscillation (TO) and oscillation slope ( TS) values, to observe the changes of TO and TS in patients with acute coronary prognosis. Results The patients were followed up (21.0 ± 11.0) months, a total of 16 patients died. The degree of sinus rhythm concussion and low left ventricular ejection fraction, age and the development of acute coronary syndrome were significantly correlated. Conclusions Sinus arrhythmia can be used as a reference index to predict the prognosis and cardiac function of acute coronary syndrome.
