Imaging Study of Lead Implant for His Bundle Pacing

The study will evaluate implant lead electrical measurements and changes over time, estimate
the correlation between lead location and selective vs non-selective His bundle pacing, and
estimate the correlation between long-term lead performance and implant characteristics. Data
from the study may be used to standardize the implant workflow to help improve the ease and
predictability of His bundle pacing implants.
