May explain activity-related pacemaker sensing issues; hypothesis-generating in this canine model, requiring human validation.
Does exercise decrease endocardial and epicardial electrogram voltages in canines with implanted pacing leads?
Exercise decreases endocardial and epicardial electrogram voltages in a canine model, suggesting a mechanism for pacemaker sensing abnormalities during physical activity.
Bricker et al. (1988) studied this question.
