一、Q 波的临床意义:正常情况下,在心室开始除极的0.04秒内的心电向量是与平均 QRS 波的综合向量相平行的,但发生急性心肌梗塞时,由于梗塞组织无电力产生,因此产生了与平均 QRS 综合向量相对应的初始向量。即在正对梗塞区的心电图导联上出现宽而深的 Q 波图形。将异常 Q 波做为冠状动脉阻塞和心肌梗塞的指标已有六十五年的历史,最初是由 Myers 等人通过尸解了解到 Q 波与坏死心肌有关系。但 Horan 等人在完成了1184例尸体心脏解剖后,却对此观点提出了异
First, the clinical significance of Q wave: Under normal circumstances, in the ventricular start within 0.04 seconds of depolarization of the ECG vector and the average QRS complex vector parallel to each other, but the occurrence of acute myocardial infarction, the infarct tissue due to no electricity , Thus generating an initial vector corresponding to the average QRS synthesis vector. That is, in the right ECG area of the infarct appears broad and deep Q-wave graphics. Abnormal Q wave as a marker of coronary occlusion and myocardial infarction has been 65 years of history, initially by Myers et al. An autopsy learned that Q waves and necrosis of the heart has a relationship. However, Horan et al. Made a different point of view after completing the necropsy of 1,184 cadaveric hearts
