The study demonstrates that subcutaneous pacing follows predictable strength-duration relationships, which can inform future device programming to optimize battery life.
Subcutaneous pacing exhibits classical excitability consistent with Lapicque's theory. Thresholds follow predictable dependencies on pulse width and waveform, indicating opportunities to optimize energy delivery safety margins. These data provide a basis for programming strategies and future device designs targeting lower energy use and extended battery life in subcutaneous and extravascular pacing systems.

Bennett et al. (Sat,) conducted a other in Subcutaneous pacing. Subcutaneous pacing was evaluated on Excitability and pacing thresholds. Subcutaneous pacing exhibits classical excitability consistent with Lapicque's theory, with thresholds following predictable dependencies on pulse width and waveform.
