Study Summary
The purpose of this study is to characterize performance of the MARVEL algorithm downloaded into the MicraTM TPS to provide atrial synchronous ventricular pacing in subjects with AV block. A sub-study will be conducted within the Marvel study, the purpose of this study is to characterize the MARVEL algorithm in patients who were enrolled in the MARVEL study, and to collect and compare the accelerometer signals and AV synchrony at a second point in time.
Primary Outcome
On an individual heartbeat basis, this is defined as a right ventricular paced or sensed R-wave associated with an ECG confirmed P-wave.
Interventions
- DEVICE MARVEL algorithm
