Why the study?
Despite favorable long-term electrical performance of Micra-TPS, a small percentage of patients develop very high pacing thresholds during follow-up.
Does a combination of implant pacing threshold and impedance predict very high pacing thresholds during long-term follow-up in patients with leadless transcatheter pacemakers?

May aid early identification of leadless pacemaker patients at risk for high thresholds; hypothesis-generating and requires prospective validation before practice change.
Does a combination of implant pacing threshold and impedance predict very high pacing thresholds during long-term follow-up in patients with leadless transcatheter pacemakers?
Implant pacing threshold and impedance can be used sequentially to predict which patients with leadless pacemakers will develop very high pacing thresholds.
