Risk stratification for sudden cardiac death in post-myocardial infarction (post-MI) patients remains a challenging task. Several electrocardiographic noninvasive risk factors (NIRFs) have been associated with adverse outcomes and were used to refine risk assessment. This study aimed to evaluate the performance of NIRFs extracted from 45-min short resting Holter ECG recordings (SHR), in predicting ventricular tachycardia inducibility with programmed ventricular stimulation (PVS) in post-MI patients with preserved left ventricular ejection fraction (LVEF).

使用 45 分钟短静息动态心电图记录对射血分数保留的心肌梗死后患者进行风险评估

心肌梗死后（MI后）患者心源性猝死的风险分层仍然是一项具有挑战性的任务。一些心电图无创危险因素 (NIRF) 与不良后果相关，并用于完善风险评估。本研究旨在评估从 45 分钟短静息动态心电图 (SHR) 记录中提取的 NIRF 的性能，预测左心室射血分数 (LVEF) 保留的 MI 后患者通过程序性心室刺激 (PVS) 诱发室性心动过速的能力。
