Overdrive atrial pacing was employed in twelve patients with suspected supraventricular tachycardia resistant to drug therapy. Eleven of these patients reverted to sinus rhythm with pacing either immediately or after a short episode of atrial fibrillation. In one patient, recordings from the atrial electrode indicated that a broad complex tachycardia was of ventricular rather than supraventricular origin. No complications were encountered and the procedure was well tolerated in all. Overdrive pacing is suggested as a safe alternative to DC cardioversion in drug-resistant supraventricular tachycardia, particularly in the presence of digitalis, in the elderly and in patients with chronic lung disease.
对12例疑似药物治疗无效的室上性心动过速患者采用超速心房起搏。其中11例患者在起搏后立即或经过短暂房颤发作后恢复窦性心律。1例患者心房电极记录显示宽QRS波心动过速起源于心室而非室上性。未出现并发症，所有患者对该操作耐受性良好。对于药物难治性室上性心动过速，特别是存在洋地黄、老年患者及慢性肺部疾病患者，建议超速起搏作为直流电复律的安全替代方法。
