本文研究心室晚电位与左室功能的关系。对65例患者分别进行了心室晚电位、冠状动脉造影和左室造影检查。结果显示,冠状动脉病变者的心室晚电位阳性组和心室晚电位阴性组其每搏量(SV)分别为60.68±22.95 ml和92.36±25.68 ml(P<0.01);心脏指数分别为3.26±1.10和4.14±1.38(L·min~(-1)/m~2)(P<0.05);射血分数分别为46.12±16.87和59.75±12.98(%)(P<0.01)。这表明心室晚电位阳性者的心功能较心室晚电位阴性者低下。
This article studies the relationship between ventricular late potentials and left ventricular function. 65 patients were ventricular late potential, coronary angiography and left ventricular angiography. The results showed that the stroke volume (SV) of patients with positive ventricular late potentials and those with negative late ventricular potentials were 60.68 ± 22.95 ml and 92.36 ± 25.68 ml (P <0.01), respectively, and the cardiac indexes were 3.26 ± 1.10 And 4.14 ± 1.38 (L · min -1 / m 2), respectively (P <0.05). The ejection fraction was 46.12 ± 16.87 and 59.75 ± 12.98% respectively (P <0.01). This indicates that the ventricular late potential positive cardiac function than late ventricular late potential negative.
