[The effect of disopyramide phosphate in extrasystole at rest and on exercise (author's transl)].
The antiarrhythmic action of disopyramide phosphate was compared to placebo in a randomized double blind trial at rest and under physical exertion in two groups each of 10 patients with extrasystoles. The exercise was carried out on the bicycle ergometer in a recumbent posture in stages of 25 watts at 2 minutes each without a break to the limit of the individual. The extrasystoles were counted at fixed registration periods. It was shown that the number of extrasystoles in the disopyramide group was significantly lower in comparison to the placebo group (P less than 0.05).
