During the second implantation, mechanically mediated device\u2013device interaction caused intermittent oversensing. Oversensing was resolved by increasing the sensing threshold, which avoided device repositioning or retrieval.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion<\/jats:title>\n                    <jats:p>Suspected mechanically mediated interaction between sequential Micra devices may cause oversensing and pacing inhibition. In patients with clinically stable condition and adequate intrinsic R-wave amplitude, programming optimization may be considered before invasive revision; however, future management should account for
