24 patients, after transmural cardiac infarction, were exposed to isometric exercise ("handgrip"). The haemodynamic response was checked by means of impedance plethysmography. The stroke volume decreased on average from 64 +/- 14 to 60 +/- 15 ml (p less than 0.05), cardiac output increased from 4.8 +/- 1.0 to 5.4 +/- 1.2 l/min. (p less than 0.01). Peripheral resistance significantly increased and left ventricular performance was non-significantly reduced. Compared with a group of healthy control, their stroke and cardiac output and cardiac work kept increasing during isometric exercise. Isometric exercise is an adequate means of checking left ventricular performance.
24例透壁性心肌梗死后的患者进行了等长运动（“握力”）。通过阻抗体积描记法检查血流动力学反应。每搏量平均从64±14ml降至60±15ml（p<0.05），心输出量从4.8±1.0l/min增加至5.4±1.2l/min（p<0.01）。外周阻力显著增加，左心室功能无显著降低。与一组健康对照相比，他们在等长运动期间每搏量、心输出量和心脏作功持续增加。等长运动是检查左心室功能的一种合适方法。
