Left ventricular performance during prolonged exercise and early recovery in healthy subjects

Abstract

The effect of semi-supine long lasting exercise to exhaustion [61 (SD 10) min] on left ventricular systolic performance was studied by echocardiography in 16 young healthy volunteers. During the incremental phase of exercise, the ejection fraction increased from 65.2 (SD 4.1)% to 80.1 (SD 4.8)% (P<0.0001), then it levelled off up to the end of exercise [81… (More)
