title: Cardiac adverse effects and acute exercise in elderly subjects.
abstract: Cardiac arrhythmias, ST segment depressions and other cardiac adverse effects are occasionally seen in relation to physical exercise in elderly people. However, the magnitude, quality, and time-dependence of these events need to be clarified. During voluntary maximal cycle ergometer exercise (CEE), immediate cardiac disturbances as a reason for exercise termination were registered in a sample of 75-year-old men and women (N=203) (population group, PG). Any referrals to hospital following cardiac incidents within 24 hours post-CEE were obtained from patient records. Ambulatory ECG was recorded 24 hours before and after CEE in 23 elderly subjects (12 men, 11 women) capable of maximal effort (Holter group, HG). In the PG, 23.4% of the men and 6.4% of the women had to terminate CEE because of cardiac disturbances. One subject was referred to hospital because of exercise-induced atrial fibrillation. In the HG, no long-lasting effect of exercise on the occurrence of cardiac disturbances was found in elderly subjects capable of maximal effort.
