A Major Determinant Focused on the ECG or Echocardiogram for Pacing-induced Cardiomyopathy (PICM) and Its Clinical Outcome (PICM Syndrome) : Prospective, Multi-center, Observational Cohort Study.

What this Trial Is About

Researchers are studying pacing-induced cardiomyopathy (PICM), a condition where chronic right ventricular pacing harms left ventricular function. This observational study focuses on ECG and echocardiogram parameters, including strain, as well as genetic factors, to identify patients at high risk of developing PICM after pacemaker implantation. The goal is to better predict who might develop PICM and understand its clinical impact over time. Participants will have ECG and echocardiogram tests before and after pacemaker implantation to assess key measurements such as QRS duration and mechanical strain. Genetic factors may also be evaluated to improve prediction of PICM occurrence. This study involves long-term follow-up to monitor the condition and its outcomes. During the study, participants will be clinically followed for up to 5 years to observe heart failure diagnosis and treatment. Researchers will also track atrial and ventricular arrhythmias, hospital admissions for heart failure, and overall mortality. The study does not involve treatment interventions but focuses on monitoring and data collection to understand PICM and its clinical outcomes.
