摘要
目的 研究急性心肌梗死患者T波峰-末时间（Tp—e时间）与恶性心律失常的关系。方法将62例急性心肌梗死患者分为恶性室性心律失常组（观察组，n=17）和非恶性室性心律失常组（对照组，n=45）。比较两组各导联和12导联平均Tp—e时间、经心率校正的Tp—e（Tp-ec）时间。结果与对照组比较，观察组各导联和12导联平均Tp—e时间及Tp—ec显著延长，差异有显著或非常显著性意义（P〈0．05或0．01）。结论Tp—e时间可以作为预测急性心肌梗死恶性室性心律失常的指标。
Objective To investigate the relationship between T peak-end interval （Tp-e） and serious ventricular arrhythmia in patients with acute myocardial infarction. Methods 62 patients with acute myocardial infarction were divided into serious arrhythmia group （n=17） and non-serious arrhythmia group （n=45）. Tp-e and heart rate-corrected Tp-e （Tp-ec） in each lead and their average values in total 12 leads were compared between the two groups. Results Tp-e and Tp-ec in each lead and their average values in total 12 leads were significantly greater in serious ventricular arrhythmia group than in non-serious arrhythmia group （P 〈 0.05 or 0.01）. Conclusion Tp-e can be used as an indicator for predicting serious ventricular arrhythmia in acute myocardial infarction.
