心室肥厚包括心室肌增厚及腔扩大。肥厚心肌的电荷数大大增加,致使除极向量增大,除极时间延长及继发性的复极程序改变。心肌肥厚后,其血液供应相对减少,又可引起原发性的复极程序改变。因此,心室肥厚主要引起QRS波群及ST段、T波的变化。一.左心室肥厚右心室位于心脏的右前上方,左心室位于其左后下方。由于左心室心肌厚度是右心室的3倍,在心室除
Ventricular hypertrophy, including ventricular mylar thickening and cavity expansion. Hypertrophic myocardium greatly increased the number of charges, resulting in depolarization vector increases, depolarization time and secondary repolarization program changes. Cardiac hypertrophy, the relative reduction of blood supply, but also can cause primary repolarization program changes. Therefore, ventricular hypertrophy mainly caused by QRS wave group and ST segment, T wave changes. I. Left ventricular hypertrophy The right ventricle is located in the right upper front of the heart, left ventricular in the lower left below. As the left ventricular myocardium is 3 times the thickness of the right ventricle, in addition to the ventricle
