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.
Despite favorable long-term electrical performance of Micra-TPS, a small percent of patients developed VHPT during follow-up. A sequential combination of IPT and impedance could allow the implanter to identify patients who will develop VHPT during long-term follow-up.
Tolosana et al. (Wed,) studied this question.
