Abstract：
UNASSIGNED: Atrial fibrillation (AF) is a prevalent cardiac condition characterized by irregular heart rhythm. Conventional non-invasive diagnostic techniques, while useful, have limitations in providing comprehensive information for treatment planning. To address this gap, electromechanical cycle length mapping (ECLM), a non-invasive echocardiography-based technique, has emerged as a promising approach. Electromechanical cycle length mapping offers quantitative and spatially specific insights into atrial electromechanical activation rate mapping, thereby enhancing our understanding of arrhythmia disease progression in AF patients.
UNASSIGNED: In this case series, we present two patient cases demonstrating the potential utility of ECLM in monitoring and evaluating treatment responses in atrial arrhythmia. The 1st case involved a 61-year-old male with persistent AF who underwent multiple procedures, including direct current cardioversion (DCCV) and radiofrequency ablation. Over three different DCCV encounters, pre- and post-procedure ECLM scans were performed, and the results showed the localization and incomplete elimination of arrhythmic triggers post-DCCV, which were used as early indicators of AF recurrence. The 2nd case involved a 71-year-old male with paroxysmal AF who also underwent cardioversion and ablation procedures. Electromechanical cycle length mapping imaging demonstrated a progressive reduction and elimination of arrhythmia triggers after each encounter, resulting in long-term maintenance of sinus rhythm.
UNASSIGNED: The findings from this case series highlight the potential of ECLM as a non-invasive imaging tool for long-term monitoring and evaluating immediate and long-term treatment responses in AF patients. The integration of ECLM with standard echocardiograms holds promise in guiding clinical decisions and improving patient outcomes in managing atrial fibrillation.

摘要：
■心房颤动(AF)是一种以不规则心律为特征的普遍心脏疾病。传统的非侵入性诊断技术，虽然有用，在为治疗计划提供全面信息方面存在局限性。为了解决这个差距，机电周期长度映射(ECLM)，一种基于非侵入性超声心动图的技术，已经成为一种有希望的方法。机电周期长度标测提供了对心房机电激活率标测的定量和空间特异性见解。从而提高我们对房颤患者心律失常疾病进展的认识。
■在这种情况下，我们介绍了2例患者病例,证明ECLM在监测和评估房性心律失常治疗反应方面的潜在效用.第一例涉及一名患有持续性房颤的61岁男性，他接受了多次手术，包括直流电复律（DCCV）和射频消融。在三次不同的DCCV遭遇中，术前和术后进行ECLM扫描，结果显示DCCV后心律失常触发因素的定位和不完全消除，作为房颤复发的早期指标。第二例涉及一名71岁的男性阵发性房颤，他也接受了心脏复律和消融手术。机电周期长度标测成像显示每次相遇后心律失常触发因素的逐渐减少和消除，导致窦性心律的长期维持。
■本病例系列的研究结果凸显了ECLM作为一种非侵入性成像工具的潜力，用于长期监测和评估房颤患者的即时和长期治疗反应。ECLM与标准超声心动图的整合有望指导临床决策并改善患者治疗房颤的结果。
