采用右胸电导纳技术检测60例急性心肌梗塞(AMI)患者的小循环心功能。结果:左心衰竭组(KillipⅡ、Ⅲ、Ⅳ级)比心功能正常组(KillipⅠ级)Q-j(PEP)延长、j-z(RVET)缩短、Q-j/j-z(RSTI)增加、hc/hz(前负荷)增高,有显著相关关系(P<0.05)。M型超声心动图测定左室射血分数(LVEF)与RSTI异常阳性率对比t=2.81,P<0.01。提示:小循环法可以早期、较灵敏、客观地反映AMI患者的心功能状况。
Right thoracic electromyography was used to detect small circulatory cardiac function in 60 patients with acute myocardial infarction (AMI). RESULTS: Q-j (PEP) prolongation in the left ventricular failure group (KillipⅡ, Ⅲ and Ⅳ) was longer than that in the normal control group (KillipⅠ), and RVT was shortened and Q-j / j- , Hc / hz (preload) increased, there was a significant correlation (P <0.05). M-mode echocardiography measured left ventricular ejection fraction (LVEF) and RSTI abnormal positive rate of t = 2.81, P <0.01. Tip: Small circulation method can be early, more sensitive and objectively reflect the AMI patients with cardiac function.
