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

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.

Inclusion Criteria:

patients consent to LP implantation surgery

Exclusion Criteria:

1. Patients with inferior vena cava thrombus, a cancer thrombus, an abnormal inferior vena cava;
2. Patients with femoral vein stenosis and tortuosity failed to accommodate the pacemaker delivery system;
3. Patients with myocardial infarction;
4. Patients who have been implanted with devices that affect the pacemaker delivery system, such as vena cava filters or tricuspid valve mechanical valves;
5. cannot understand or are unwilling to give informed consent.
