简要总结

The purpose of this study is to evaluate different types of leads (wires) that are connected to your pacemaker (an implanted device which assists your heart function) to understand how the shape and motion of your previously implanted lead changes in the body.

结局指标

主要结局

Number of Participants With in Vivo Cyclic Mean Curvature of Pacing and Defibrillation Leads in the Extravenous Region Determined During Specified Arm Movements

时间窗: Approximately 1 month

Measure dynamic in vivo curvature of RV pacing and defibrillator leads in the extravenous and intracardiac anatomy \*\*\*In vivo cyclic mean curvature of RV pacing and defibrillation leads in the extravenous region will be determined during specified arm movements. The relationship between lead stiffness and curvature will be evaluated.

Number of Participants With in Vivo Cyclic Mean Curvature of Pacing and Defibrillation Leads in the Connector Region Determined During Specified Arm Movements

时间窗: Approximately 1 month

Assess the relationship between subject and implant variables and lead curvature \*\*\*In vivo cyclic mean curvature of RV pacing and defibrillation leads in the connector region were determined during specified arm movements. The relationship between lead stiffness and curvature was evaluated.

Number of Participants With in Vivo Cyclic Mean Curvature of Pacing and Defibrillation Leads in the Intracardiac Region Determined During Two or More Cardiac Cycles

时间窗: Approximately 1 month

Measure the relationship between lead bending stiffness and in vivo curvature \*\*\*In vivo cyclic mean curvature of RV pacing and defibrillation leads in the intracardiac region will be determined during two or more cardiac cycles. The relationship between lead stiffness and curvature will be evaluated.
