  • Title: Sinus node echoes and concealed concealed conduction: additional sinus node phenomena confirmed in man by direct sinus node electrography.
    Author: Reiffel JA, Bigger JT, Ferrick K, Livelli FD, Gliklich J, Wang P, Bosner R.
    Journal: J Electrocardiol; 1985 Jul; 18(3):259-66. PubMed ID: 4031729.
    Abstract:
    Direct sinus node electrography has been previously used to assess several aspects of sinus node physiology: sinus node pauses, overdrive suppression, sinoatrial entrance block. This report presents data in which sinus node electrograms confirm two additional physiologic phenomena in man: concealed conduction in the sinoatrial junction and sinus node reentry. These findings verify the presence of previously suspected phenomena by careful deductive analysis of electrocardiographic and electrographic tracings.
