[Our experience in treatment of the inhibition of demand pacemaker by muscle potentials (author's transl)].
The inhibition of demand pacemakers by muscular potentials is rarely described in the literature. The Authors have found an interference of the pectoralis muscle's electric activity with pacemakers in 4 patients suffering from occasional faints. Extending this study to a group of 10 asymptomatic electrostimulated patients, pacemaker's inhibition by sub-maximal contraction of pectoralis major muscle has been found in 9 of them. The 4 symptomatic patients have been operated displacing the battery near the sternum. The poor thickness of the pectoralis muscle's fibres suggested the treatment. The controls performed from 2 to 8 months respectively have shown disappearance of the symptoms.
