Improvement in HRR paralleled that in BRS in TR patients (from 3.2 +/- 0.3 to 5.3 +/- 0.8 ms/mmHg; P < 0.001), whereas no significant change was evident in UTR patients (from 3.5 +/- 0 to 4.0 +/- 0.4 ms/mmHg; P = 0.230). Our data show that HRR in the 2nd min after the cessation of a cycle ergometer exercise test increased in coronary artery patients after an exercise training period.

HRR might provide an additional simple marker of the effectiveness of physical training programs in cardiac patients.

Abstract

Effects of residential exercise training on heart rate recovery in coronary artery patients. Am J Physiol Heart Circ Physiol 292: H510-H515, 2007. First published September 15, 2006; doi:10.1152/ajpheart. 00748.2006.-The aims of the present study are twofold: 1) to investigate whether heart rate recovery (HRR) after a cycle ergometry test is affected by exercise training and 2) to test the ability of HRR to replicate the baroreflex sensitivity (BRS) changes that occur in response to an exercise training program in coronary artery patients. We randomized 82 coronary artery patients undergoing a residential cardiac rehabilitation program to an exercise training group (TR; n = 43) and an untrained group (UTR; n = 39). All of the patients underwent an exercise test before and after the rehabilitation program. HRR was recorded at the end of the 1st and 2nd min after exercise.
