摘要: 本研究探讨心脏电生理平衡指数等心电图(ECG)参数预测变异型心绞痛合并恶性室性心律失常的价值。选取82例变异型心绞痛合并恶性室性心律失常患者作为观察组,同时选取100例变异型心绞痛患者作为对照组,分析比较两组ECG参数差异;同时比较复发组和未复发组ECG参数差异。观察组QT、心脏电生理平衡指数和TpTe明显高于对照组(P<0.05),而JTp明显低于对照组(P<0.05);共有38例患者复发心绞痛;复发患者年龄、QT、心脏电生理平衡指数和TpTe明显高于未复发患者(P<0.05),而JTp明显低于未复发患者(P<0.05)。ECG参数预测变异型心绞痛合并恶性室性心律失常,以及心绞痛复发方面有一定应用价值。

Abstract: This study explored the value of electrocardiogram (ECG) parameters such as the cardiac electrophysiological balance index in predicting variant angina pectoris complicated with malignant ventricular arrhythmia. 82 patients with variant angina pectoris complicated with malignant ventricular arrhythmia were selected as the observation group, and 100 patients with variant angina pectoris only were selected as the control group, the differences of ECG parameters between the two groups were analyzed and compared, at the same time the differences of ECG parameters between recurrent group and non-recurrent group were compared. The QT, cardiac electrophysiological balance index and TpTe in the observation group were significantly higher than those in the control group (P<0.05), while JTp was significantly lower than those in the control group (P<0.05). A total of 38 patients had recurrent angina pectoris. The age, QT, cardiac electrophysiological balance index and TpTe of recurrent patients were significantly higher than those of non-recurrent patients (P<0.05), while JTp was significantly lower than those of non-recurrent patients (P<0.05). ECG parameters have certain application value in predicting variant angina pectoris complicated with malignant ventricular arrhythmia and angina pectoris recurrence.
