Overshoot phenomenon of oxygen uptake during recovery from maximal exercise in patients with previous myocardial infarction

The overshoot in oxygen uptake ( V̇ O 2 overshoot) during recovery from maximal exercise is thought to reflect an overshoot in cardiac output. We investigated whether this phenomenon is related to cardiopulmonary function during exercise in cardiac patients. A total of 201 consecutive patients with previous myocardial infarction underwent cardiopulmonary exercise testing (CPX). An apparent V̇ O 2 overshoot during the recovery from CPX (6.5 ± 8.1
