Abstract:
:In a patient with the sick sinus syndrome and near syncope a prolonged sinus pause was documented and reproduced thereafter during sustained deep inspiration. Administration of intravenous atropine abolished this phenomenon, most probably indicating a hyperresponsiveness of the sinus node and AV junction to a vagotonic reflex.
