DDD pacing may be an effective treatment of recurrent atrial arrhythmias, although not all authors are of this opinion. Twenty patients with age variable from 70 to 87 years, 12 men and 8 women, underwent transvenous implant of DDD pacemakers, for brady-tachy syndrome, a consequence of sick sinus syndrome (SSS). Atrial pacing in DDD mode in selected patients, prevent the rise of atrial arrhythmias, atrial flutter being more sensitive than atrial fibrillation. However, it is obvious that in these patients, the antiarrhythmic therapy, without safety-pacemaker, is bound to fail, as it cannot applied at full dosage for real danger to worsen their bradycardia.
DDD起搏可能是治疗复发性房性心律失常的一种有效方法，尽管并非所有作者都持这种观点。20例年龄在70至87岁之间的患者，其中12例男性和8例女性，因病态窦房结综合征（SSS）导致的快慢综合征接受了DDD起搏器的经静脉植入。在选定的患者中采用DDD模式进行心房起搏，可预防房性心律失常的发生，心房扑动比心房颤动更敏感。然而，很明显，在这些患者中，没有安全起搏器的抗心律失常治疗必然会失败，因为由于存在使心动过缓恶化的实际风险，无法以全剂量应用。
