The unipolar pulse generator systems were tested in 220 patients (96 VVIM, 97 VVIO, 27 physiological systems) to determine the incidence of sensing interference with muscle potentials. 23% exhibited oversensing, with a sex distribution of 32% for males and 15% for females. The interference was observed more often in VVIM pacemakers at nominal setting (35%) than in VVIO pacemakers (11%). In DDD pacemakers both inhibition and triggering of ventricular stimulation was observed. Among the 23 patients with persisting syncope or dizziness after implantation of the pacemaker, the symptoms were observed during physical activity only in 5. In these 5 the underlying arrhythmia was tachycardia in 3 and inhibition of the pacemaker by muscle potentials in only one patient.
对220例患者（96例VVIM型、97例VVIO型、27例生理型系统）的单极脉冲发生器系统进行了测试，以确定感知肌肉电位干扰的发生率。23%的患者出现感知过度，其中男性占32%，女性占15%。在标称设置下，VVIM起搏器中出现干扰的情况（35%）比VVIO起搏器（11%）更常见。在DDD起搏器中，观察到心室刺激的抑制和触发。在植入起搏器后仍有持续晕厥或头晕的23例患者中，仅5例在体力活动期间出现症状。在这5例患者中，3例潜在心律失常为心动过速，仅1例患者是肌肉电位抑制起搏器。
