Key result
Physical exercise did not significantly alter pacing threshold, impedance, R wave amplitude, or energy consumption compared to rest in patients with ventricular demand pacemakers.

Resting pacemaker parameters may remain reliable during exercise; leaves open prospective validation before guiding programming.

Does physical exercise alter pacing threshold, impedance, and R wave amplitude compared to rest in patients with ventricular demand pacemakers?
Pacemaker programming based on resting measurements is reliable and safe during exercise, as pacing thresholds, impedance, and R wave amplitudes do not significantly change.
Schuchert et al. (1990) conducted an observational in Patients with a multiprogrammable ventricular demand pacemaker (n=22). Physical exercise vs. Rest was evaluated on Voltage threshold, impedance, R wave amplitude and energy consumption. Physical exercise did not significantly alter pacing threshold, impedance, R wave amplitude, or energy consumption compared to rest in patients with ventricular demand pacemakers.
