Changes of Heart Rates at Rest and on Exercise during Cardiac Sports-Rehabilitation in Patients with Coronary Artery Diseas
【Supercategory：7. DESCENTE SPORTS SCIENCE Subcategory：7.11 Vol.11】
Twenty-seven patients with coronary artery disease (26 with old myocardial infarction & 7 with coronary-artery bypass-graft), who were enrolled in the Cardiac Sports Rehabilitation Program, were studied with regard to the heart-rate response. Twenty-six were male and one female, age ranged between 45 and 71 with average 56.6 years. The patients were classified into two groups ; Group H, 9 patients with the resting heart-rate at the initial treadmill exercise study ≧ 90 bpm, and Group N, 18 patients with the resting heart rate < 90 bpm.
Resting heart rates and peak heart rates during the rehabilitation program in Group H were significantly higher than those in Group N. Heart rates during the symptom-limited exercise tests were also higher in Group H than in Group N. Patients in both groups showed a tendency to decrease in heart rates during the 3-month rehabilitation period and no significant difference in heart rate response or exercise capacity was noted between the two groups.
Thus, patients who show a tendency of tachycardia seem to be able to perform cardiac rehabilitation with the target heart rate calculated from Karvonen's formula and essentially same rehabilitation effects will be expected as normal heart-rate responders.
