Lead type and pacing rate should inform evoked response interpretation; leaves open effects on chronic sensing and thresholds.
How do electrode characteristics and pacing rate influence the morphology of the unipolar endocardial paced evoked response in patients prior to pacemaker implantation?
Electrode characteristics and pacing rate significantly influence the morphology of the unipolar endocardial paced evoked response, though spontaneous signals have low predictive value for ERS morphology.
Brouwer et al. (1990) studied this question.
