About

Comparison of cardiac synchronization and tricuspid regurgitation with or without leadless pacemaker pacing in different site

Full description

Right ventricular pacing might lead to pacing-induced cardiomyopathy by dyssynchrony and tricuspid regurgitation. Pacing at various sites had different effects on synchrony and tricuspid regurgitation. This study is to observe the effect of leadless pacemaker implantation in different regions on ventricular synchronization and tricuspid regurgitation. Ultrasound and ECG parameter indices are applied.

Enrollment: 40 estimated patients

Sex: All

Volunteers: No Healthy Volunteers
