摘要

背景和目的以前的心脏植入式电子装置（cied）可以自动监测、诊断和存储心房或室性心动过速的心内电图（EGMs）。雅培新一代cied提供事件前EGM存储（Pre-EGM），记录心律失常事件前的心电活动。本研究确定了前egm是否为心律失常事件提供了额外的诊断信息。方法我们于2015年4月- 2023年7月在北京医院连续招募92例具有egm前功能的cied患者。设备根据内置算法报告了1543个事件。三位心脏电生理学专家对每个事件独立解释两次：首先仅使用触发后的egm，然后结合egm前的数据进行最终分类。结果在1260例自动模式切换（AMS）事件中，994例（78.89%）仅使用egm诊断，而1251例（99.29%）使用preegm合并诊断，诊断率提高了20.40%。在包括高心室率、室性早搏、室上性心动过速和室性心动过速在内的187例心律失常事件中，124例（66.31%）仅使用egm诊断，而183例（97.86%）使用egm前诊断，改善了31.55%。结论仅依靠事件后的EGMs来确定事件是不够精确的。预egm功能为cied记录事件的明确诊断提供了全面的信息，代表了植入设备后的优越分析。

Analysis of the diagnostic value of pre-event intracardiac electrogram (pre-EGM) storage function in cardiac electronic implantable devices for arrhythmia diagnosis

Background and aims

Previous cardiac implantable electronic devices (CIEDs) automatically monitored, diagnosed, and stored atrial or ventricular tachyarrhythmias as intracardiac electrograms (EGMs). Abbott's new-generation CIEDs offer pre-event EGM storage (Pre-EGM), recording cardiac electrical activity before arrhythmic events. This study determines whether Pre-EGM provides additional diagnostic information for arrhythmic events.

Methods

We consecutively enrolled 92 patients with CIEDs featuring Pre-EGM functionality at Beijing Hospital (April 2015–July 2023). Devices reported 1543 events based on built-in algorithms. Three cardiac electrophysiology experts independently interpreted each event twice: first using only post-trigger EGMs, then incorporating Pre-EGM data for final classification.

Results

Among 1260 automatic mode switch (AMS) events, 994 (78.89 %) were diagnosed using EGM-only interpretation versus 1251 (99.29 %) with Pre-EGM incorporation, representing a 20.40 % improvement in diagnostic yield. Among 187 arrhythmic events including high ventricular rate, premature ventricular contractions, supraventricular tachycardia, and ventricular tachycardia, 124 (66.31 %) were diagnosed using EGM-only versus 183 (97.86 %) with Pre-EGM, representing 31.55 % improvement.

Conclusions

Relying solely on post-event EGMs for event determination is insufficiently precise. Pre-EGM functionality provides comprehensive information for definitive diagnosis of CIED-recorded events, representing superior post-implantation device analysis.

期刊介绍： The International Journal of Cardiology is devoted to cardiology in the broadest sense. Both basic research and clinical papers can be submitted. The journal serves the interest of both practicing clinicians and researchers. In addition to original papers, we are launching a range of new manuscript types, including Consensus and Position Papers, Systematic Reviews, Meta-analyses, and Short communications. Case reports are no longer acceptable. Controversial techniques, issues on health policy and social medicine are discussed and serve as useful tools for encouraging debate.
