A patient with refractory paroxysmal atrioventricular nodal re-entrant tachycardia had required direct current cardioversion to terminate attacks on 83 occasions. A dual demand pacemaker was implanted to sense and interrupt attacks of tachycardia automatically. The pacing electrode was positioned in the proximal coronary sinus near to the atrioventricular node; a site from which fixed rate underdrive pacing successfully interrupted attacks throughout a trial period of one week, with a lead left in this position on a temporary basis. Complete control of the arrhythmia was obtained in the six months after pacemaker implantation.
一名患有难治性阵发性房室结折返性心动过速的患者曾83次需要直流电复律来终止发作。植入了一个双按需起搏器以自动感知并中断心动过速发作。起搏电极置于靠近房室结的冠状窦近端；在为期一周的试验期内，从该部位进行的固定频率超速抑制起搏成功中断了发作，并暂时将导线留在该位置。起搏器植入后的六个月内实现了心律失常的完全控制。
