The CT-verified Data Collection Study to Investigate the Correlation Between the Leadless Pacemaker Tip Location and Echo, ECG

• Status: Active Not Recruiting

Summary

The goal of this observational study is to assess inter-/intra- ventricular synchrony and ECG characteristics in relation to Micra tip location. The secondary objective is (1) to identify an optimal Micra pacing location to improve LV function, (2) to investigate the correlation between Micra tip location and tricuspid regurgitation, and (3) to investigate whether Micra location would impact AV synchrony. Patients with pacing indications who plan to receive Micra AV implantation will be recruited.

Conditions

• Bradycardia Sinus
• AV Block
• Atrial Fibrillation (AF)

Interventions
