摘要
目的探讨变异型心绞痛（VAP）患者发作时Tp—e间期、校正Tp—e间期（Tp-ec）、Tp—e／QT对恶性心律失常事件发生的预测价值。方法选择变异性心绞痛患者62例，变异型心绞痛发作时并发恶性心律失常为观察组，变异型心绞痛发作时未并发恶性心律失常为对照组，测算两组ST段抬高导联的Tp—e间期、校正的Tp—e、Tp-e／QT比值，并进行统计学分析。结果观察组与对照组相比，Tp-e、Tp—ec间期明显延长，Tp—e／QT值明显增大，且差异有统计学意义（P〈0．05）；分别以Tp—e115ms、Tp—ec113ms、Tp—e／QT值0．28为节点，分析变异型心绞痛与恶性心律失常发生的相关性，差异均有统计学意义（P〈0．05）。结论Tp—e、Tp—ec、Tp-e／QT有望成为预测变异性心绞痛患者发生恶性心律失常的心电学指标。
Objective To predictive the value of Tp-e interval, corrected Tp-e （Tp-ec）, Tp-e/QT on occurrence of malignant arrhythmia events in patients with variant angina. Methods A total of 62 cases of variant angina pectoris were selected. According to the attack was complicated with malignant arrhythmia or not, they were divided into observation group and control group. Different indixes of Tp-e interval, corrected Tp-e and Tp-e/QT ratio were measured and contrasted in ECG leads that ST segment were elevated in these two group patients. Results Compared with control group, the levels of Tp-e, Tp-ec in the observation group were significantly prolonged, Tp - e/QT was significantly increased, and the differences were significant （ P 〈 0.05 ）. The occurrence of malignant arrhythmia events had signifi- cant difference（P 〈0. 05）, when joint point of Tp-e interval was 115 ms and that corrected Tp-e was 113 ms and that of Tp-e/QT ratio was 0. 28 in patients with variant angina. Conclusions Tp-e, Tp-ec, Tp-e/QT are the indixes to predict malignant arrhythmia events in patients with variant anzina.
