May affect device sensing thresholds; leaves open translation from canine models to clinical practice.
Hughes et al. (1976) studied this question. Small surface area pacemaker electrodes vs. Larger surface area electrodes was evaluated on Endocardial and intramyocardial R-wave potentials. Small surface area pacemaker electrodes directly correlated with decreased amplitude of transmitted R-wave potentials in a study of 10 dogs.
