Study design:

Cohort study 

研究目的:

主要目的:探讨 HRV 对严重 DMR 患者室性心律失常的预测作用。 次要目的:行亚组分析,根据患者 DMR 病因(MVP 或其他)、脱垂类型(单区脱垂 或多区脱垂)等情况,探讨不同亚组 DMR 发生 VAs 的异同。  

Objectives of Study:

Main objective: To investigate the predictive role of HRV for ventricular arrhythmia in patients with severe DMR. Secondary objective: Conduct subgroup analyses based on factors such as the etiology of DMR (MVP or other) and prolapse type (single-segment or multi-segment prolapse) to investigate the differences and similarities in the occurrence of VAs across different DMR subgroups.
