急性冠脉综合征缺血性J波的临床意义

The clinical significance of ischemic J waves in patients with acute coronary syndrome

目的探讨动态心电图缺血性J波在急性冠脉综合征(acute coronary syndrome,ACS)的诊断价值。方法将30例急性冠脉综合征患者出现缺血性J波分为A组,将30例早期复极患者分为B组,回顾分析两组动态心电图、心脏事件情况。结果 A组缺血性J波伴ST段上抬,发生严重室性心律失常大于B组有显著差异(p<0.05)。结论动态心电图监测中ASC患者出现缺血性J波同时ST段抬高常提示心电活动不稳定,易诱发严重室性心律失常,值得临床高度重视。

Objective To explore the diagnostic valuation of ischemic J waves in dynamic electroc, ardiogram （DCG） for patients with acute coronary syndrome（ACS）. Methods 30 cases of ACS with ischemic J waves were divided into A group, other 30 cases of early depolarization were divided into B group. The data of DCG and heart incident were retrospectively analyzed. Results The malignant ventricular arrhythmia presented more in group A than in group B, There are significant difference （/）〈0.05）. Conclusion The appearance of ischemic J waves together with ST-segment elevation in the monitoring of DCG implicate electrocardial activity is unsteady, closely related to malignant ventricular arrhythmia. It should bring to high attention in the clinical work.
