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.
肌肉电位对按需型起搏器的抑制在文献中鲜有描述。作者在4例偶尔昏厥的患者中发现胸肌电活动对起搏器产生干扰。将该研究扩展至10例无症状电刺激患者组成的一组人群后，发现其中9例患者在胸大肌次最大收缩时起搏器受到抑制。4例有症状的患者接受了手术，将电池移至靠近胸骨处。胸肌纤维较薄提示了这种治疗方法。分别在术后2至8个月进行的对照显示症状消失。
