摘要
目的探讨冠心病(CHD)患者动态心电图(AECG)心律失常和心肌缺血的特点,对其临床价值进行评价和讨论。方法回顾性分析150例CHD患者的AECG,与同期健康体检者进行对比,观察两组心律失常、ST段变化的心电学特点,并对检出率进行统计学分析。结果CHD组发生Lown》3级的室性心律失常和ST段阳性改变者与对照组相比,有显著性差异(P<0.05)。且CHD组无症状心肌缺血发生率远高于有症状者。结论AECG是一项有效、无创的检查手段,对发现冠心病心律失常和诊断心肌缺血,尤其是无症状心肌缺血很有价值。
Objective To analyze the ambulatory electrocardiogram （AECG） in the coronary heart disease （CHD） patients. Methods 150 patients with CHD and 145 healthy controls, all subjects underwent AECG. Results Compared with the control group, the percents of Lown》3 级. ventricular arrhythmia and positive changes of ST-segment depression were higher significantly（P〈0.05）. The patients with silent myocardial ischernia were more than that with chest pain. Conclusions AECG is a sensitive and noninvasive method. It could be utilized to detect arrhythmia and myocardial ischemia in CHD patients, special silent myocardial isehemia.
