Why the study?
Does the evaluation of secondary pauses following rapid atrial pacing improve the identification of sinus node dysfunction compared to standard SNRTmax?
Does the evaluation of secondary pauses following rapid atrial pacing improve the identification of sinus node dysfunction compared to standard SNRTmax?
Secondary pauses following rapid atrial pacing are closely associated with spontaneous SA block or sinus pauses and may be more sensitive than SNRTmax for identifying sinus node dysfunction.
No takes yet. Share an insight, caveat, or question.
Secondary pauses may enhance sinus node dysfunction detection beyond SNRTmax; leaves open prospective validation before clinical adoption.
Benditt et al. (1976) studied this question.
