Why the study?
Does constant atrial pacing accurately estimate sinoatrial conduction time compared to premature atrial stimulation and true SACT in isolated rabbit right atrial preparations?
Does constant atrial pacing accurately estimate sinoatrial conduction time compared to premature atrial stimulation and true SACT in isolated rabbit right atrial preparations?
Constant atrial pacing provides estimates of sinoatrial conduction time that correlate moderately with true SACT, but accuracy is limited by electrophysiological changes and capture failure.
No takes yet. Share an insight, caveat, or question.
CAP estimates show limited accuracy for SACT in rabbit atria; leaves open its validity for clinical sinus node assessment.
Grant et al. (1979) studied this question.
