Two patients who had DDD pacemakers inserted for symptomatic sick sinus syndrome developed sustained upper-rate limit pacing. It was demonstrated in these two patients that pacemaker-mediated tachycardia was due to tracking of atrial flutter. DDD pacemakers should be used with caution in patients with the sick sinus syndrome and associated atrial tachyarrhythmias. Medical treatment of recurrent atrial tachyarrhythmias may allow patients to remain in the DDD mode.
两名因症状性病态窦房结综合征植入DDD起搏器的患者出现了持续性上限频率起搏。在这两名患者中证实,起搏器介导的心动过速是由于心房扑动的跟踪所致。对于患有病态窦房结综合征及相关房性快速性心律失常的患者,应谨慎使用DDD起搏器。对复发性房性快速性心律失常进行药物治疗可能使患者能够继续使用DDD模式。
