心脏正常时,心电向量VCG横面(H)T环运行方向一般与QRS环的运行方向一致,均呈逆钟向运转。当T环在H面上呈顺钟向(CW)运行时,多认为是心肌复极异常,常提示心肌缺血或心肌受损。为探讨其临床意义,本文对52例H面T环CW运行患者进行了左心功能测定,并与50例正常人进行对比分析。1 对象和方法正常组50例,男性23例,女性27例,年龄19～65岁(平均41岁)。无任何心血管病史,血压、体检、胸透、ECG、VCG
When the heart is normal, the VCG cross-sectional (H) T-ring running direction is generally the same as the running direction of the QRS ring, and both of them are operated in a counterclockwise direction. When the T-ring in the H surface was clockwise (CW) run, more thought to be myocardial repolarization, often prompted myocardial ischemia or myocardial damage. In order to explore its clinical significance, we performed a left ventricular function test in 52 patients with H-plane T-ring CW and compared with 50 normal controls. 1 object and method normal group of 50 patients, 23 males and 27 females, aged 19 to 65 years (mean 41 years).
