对4组共223例不同检测者的ECG和VCG的T环4项指标进行分析。结果表明:1.心肌缺血时VCG的T环改变比ECG上的T波和ST段改变更为敏感;2.当T环电压小于0.3mV、T环长/宽比值和T/QRS比值变小时结合临床可考虑为早期心肌供血不足。
Four groups of 223 ECGs and VCG T-ring 4 indexes were analyzed in 223 different subjects. The results showed that: 1. The change of T-ring in VCG is more sensitive than the change of T-wave and ST-segment in ECG when the myocardial ischemia; 2. When the T-ring voltage is less than 0.3mV, the ratio of T-ring length to width and T / Hours combined with clinical may consider early myocardial insufficiency.
