Examinations in 28 pairs of twins who were studied by bicycle ergometry during a "pure" graded exercise and an exercise during oral administration of anapriline have shown that the functional features of the heart make some contribution to cardiovascular implementation of the "pure" graded exercise. When given exercise and anapriline, energy processes play a role in its implementation. It is suggested that exercise + anapriline will cause substantial metabolic changes which can be essential in cardiac decompensation if exercise is not limited in the use of beta-blockers.
