本文分析76例窦性心律伴单源性室性早搏病人的心电向量图特征。男性45例,女性31例,年龄21—70岁。向量图采用Frank导联系统。卧位,胸部电极置于第5肋间水平。入选病例均描记窦性搏动及室早向量图各一份。病人分两组:非器质性心脏病人组,临床除室早外各种检查均在正常范围内,共35例。器质性心脏病人组为41例,其中冠心病人21例,高血压病8例,慢性肺原性心脏病5例,风湿性瓣膜病1例,病毒性心肌炎3例,心肌病3例。本文采用的异常心功能标准是PEP/LVET≥0.45及/或LVET≤0.5。
This article analyzes 76 cases of sinus rhythm with single source ventricular premature beats in patients with ECG vector chart features. 45 males and 31 females, aged 21-70 years old. Vector diagram using Frank lead system. In supine position, the chest electrode was placed on the 5th intercostal level. Selected cases were recorded sinus beats and ventricular early vector chart of each one. Patients were divided into two groups: non-organic heart disease group, clinical examination room early in various tests were in the normal range, a total of 35 cases. Organic heart disease group was 41 cases, of which 21 cases of coronary heart disease, hypertension in 8 cases, 5 cases of chronic pulmonary heart disease, rheumatic valvular disease in 1 case, 3 cases of viral myocarditis, cardiomyopathy in 3 cases. Abnormal cardiac function criteria used herein are PEP / LVET ≧ 0.45 and / or LVET ≦ 0.5.
