心肌缺血少见的几种心电图变化

目的观察心肌缺血患者的少见心电图图形变化特征。方法回顾性分析215例心肌缺血患者的心电图资料,归纳几种少见的心电图特征。结果 215例患者的心电图资料中:①出现J波者16例,其中2例J波与T波融合且振幅逐波交替;②QTc间期改变者44例,其中延长者25例,缩短者19例;③出现(类)右束支阻滞者23例,其中14例持续存在,9例为一过性出现;④出现各种等位性Q波者106例,其中9例表现为新出现的s波。结论心肌缺血可表现为J波出现,QTc间期的改变、(类)右束支阻滞、s波型等位性Q波等。

Several rare chang es in the electrocardiogram with myocardial ischemia

Objective To study the characteristics of ECG ehangs in myocardial ischemia. Methods Retrospective analysis of EGG data of 215 patients with myocardial ischemia to observe several rare ECG characters. Results In the 215 patients with myocardial ischemia, the ECG characteristics were the following up：①16 cases of ischemic J wave including 2 cases of J wave altemation;②14 cases had changes of QTc interval, including 25 cases of QTc prolongation, 19 patients of QTc interval shortening;③23 patients had right bundle branch block （-like QRS）,including 14 cases whose right bundle branch block （-like QRS） were persistent, 9 cases whose right bundle branch block （-like QRS） were transient;④106 eases had all kinds of isoelectric Q wave, including 9 cases of s wave could be seen. Condusion lschemie J wave,QTe interval change, resembling right bundle branch block, and isoelectric Q wave（ like s wave）could see in myocardial isebemia.
