引言：在植入永久性起搏器的患者中，模式切换事件通常被解释为房性快速性心律失常的替代标记。本研究的目的是确定自动模式切换算法的准确性，在患者的永久性起搏器的房性心动过缓syndrome的诊断方法和结果：40例心动过速-心动过缓综合征和美敦力Thera或卡帕700永久性起搏器进行霍尔特监测。比较起搏器记录的每次模式转换发作的日期、发作时间和持续时间以及霍尔特监护仪记录的每次房性快速性心律失常发作。16例患者在霍尔特监测中共记录了54例房性快速性心律失常（47例房颤，7例房扑）。霍尔特数据与起搏器询问的比较表明，54次房性快速性心律失常发作中有53次（98.1%）导致模式切换，其中1次为窦性心律期间的13秒模式切换。模式转换对房性快速性心律失常持续时间的敏感性和特异性分别为98.1%和100%。该算法检测到98.9%的房颤总持续时间和96.4%的心房扑动总持续时间。结论：在心动过速-心动过缓综合征患者和具有这些模式切换算法的永久起搏器中，模式切换事件是房性快速性心律失常的可靠替代标记。因此，模式转换可作为临床决策和进一步研究房性快速性心律失常的自然史和负担的有价值的工具。（J.E.

Introduction:In patients with permanent pacemakers, mode switching events often are interpreted as surrogate markers for atrial tachyarrhythmias. The aim of this study was to determine the accuracy of automatic mode switching algorithms in patients with permanent pacemakers for the diagnosis of atrial tachyarrhythmias.Methods and Results:Forty patients with tachycardia‐bradycardia syndrome and Medtronic Thera or Kappa 700 permanent pacemakers underwent Holter monitoring. Date, time of onset, and duration of each mode switch episode as recorded by the pacemaker and each atrial tachyarrhythmia episode as recorded by the Holter monitor were compared. Sixteen patients had a total of 54 atrial tachyarrhythmias documented on Holter monitoring (47 atrial fibrillation, 7 atrial flutter). Comparison of Holter data with pacemaker interrogation demonstrated that 53 (98.1%) of 54 atrial tachyarrhythmia episodes resulted in mode switching with one 13‐second episode of mode switching during sinus rhythm. The sensitivity and specificity of mode switching for the duration of atrial tachyarrhythmias were 98.1% and 100%, respectively. The algorithms detected 98.9% of the total duration of atrial fibrillation and 96.4% of the total duration of atrial flutter.Conclusion:In patients with tachycardia‐bradycardia syndrome and permanent pacemakers having these mode switching algorithms, mode switching events are reliable surrogate markers for atrial tachyarrhythmias. Therefore, mode switching may serve as a valuable tool for clinical decision making and further research into the natural history and burden of atrial tachyarrhythmias.(J Cardiovasc Electrophysiol, Vol. 15, pp. 773‐777, July 2004)
