心电向量图向右后向量增大,是右室肥厚的特征,但也可是左室后基底部肥厚的表现,有鉴别的必要。本文通过对30例有向右后向量增大的慢性肺心病人及30例存在左室后基底部肥厚的高血压等疾病患者心电向量图的观察分析,提出了根据额面最大QRS向量的方位及旋转方向等6项心电向量图改变的差别进行轻度右室肥厚与左室后基底部肥厚的鉴别诊断。
ECG vector diagram to the right after the vector increases, is characterized by hypertrophy of the right ventricle, but also the performance of the left ventricular base hypertrophy, the identification of the necessary. In this paper, 30 patients with rightward posterior vector enlargement of chronic pulmonary heart disease and 30 cases of left ventricular hypertrophy hypertensive hypertension and other diseases in patients with ECG vector chart observation and analysis, the proposed maximum QRS vector Orientation and rotation direction of 6 ECG changes in the difference between mild right ventricular hypertrophy and left ventricular base hypertrophy after the differential diagnosis.
