对86例前壁心肌梗塞患者的心电图V_3～V_6导联U波直立、低平及倒置等变化与异常Q波数目及射血前间期/左室射血时间比值进行分析,结果提示,U波改变的程度与心肌梗塞面积及心功能损害程度有关,反映出病情的严重程度。
The changes of U wave of ECG in V_3 ~ V_6 ECG of 86 patients with anterior myocardial infarction were analyzed with the number of abnormal Q wave and the ratio of ejection duration to left ventricular ejection time. The results showed that U The extent of the change in the wave is related to the extent of myocardial infarction and the extent of impairment of cardiac function, reflecting the severity of the condition.
