Developmental phase
Assessment
Primary outcomes
AV synchronization rate (device data AM-Vp and AM-Vs rates) in relation to various parameters
1) Relationship with patient background (age, BMI, NYHA classification, frailty, underlying disease, etc.)
2) Pacemaker parameters at the time of implantation
3) Position of implantation (postoperative imaging: CT, echocardiography)
4) Parameter setting after implantation
Key secondary outcomes
1) Changes in Cardiac Functional Status by Adjustment of AV Synchronization Ratio
2) Change in AV synchrony rate over time
