QRS波振幅的形成机制一直无定论,但与心室壁的厚度和心室的半径明显相关。当心电图导联QRS波振幅增高时,常提示心室肥厚或扩大。而QRS波振幅降低形成低电压时则认为与心衰、心包积液、肺气肿等病因相关。心电图低电压分别有肢体导联低电压、胸前导联低电压,全导联低电压,而左胸导联低电压则提及较少。[定义]标准12导联心电图中,当V4~V6导联或V4、V5导联或V5、V6导联QRS波振幅最高正向波与
The mechanism of QRS wave amplitude formation has been inconclusive, but is significantly related to the thickness of the ventricular wall and the radius of the ventricle. When the ECG lead QRS wave amplitude increased, often prompted ventricular hypertrophy or enlargement. The QRS wave amplitude is reduced to form a low voltage is considered and heart failure, pericardial effusion, emphysema and other causes. ECG low voltage, respectively, the limb lead low voltage, chest lead low voltage, all leads low voltage, while the left chest lead low voltage is mentioned less. [Definition] In the standard 12-lead electrocardiogram, when QR4 wave amplitude of V4 ~ V6 lead or V4, V5 lead or V5, V6 lead is the highest,
