title = "Sinus node echoes and concealed concealed conduction: Additional sinus node phenomena confirmed in man by direct sinus node electrography",
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.",

note = "Funding Information: Direct sinus node electrograms (SNE) have provided a means to directly assess in vivo human sinus node physiology and pathophysiology ~9. Prior to their development, our knowledge of human sinus node physiology was based upon extrapolation from animal investigation, upon observations made with indirect electrophysiological techniques or pharmacological manipulation, 10 or upon deductive electrocardiographic reasoning, usually by analogy to the A-V node 11. Since 1980, many of the conclusions about human sinus nodal and perinodal physiology drawn from the previous indirect analyses have been re-examined by studies using direct sinus node recordings. Those have shown that both sinus node automaticity and/or sinoatrial conduction may be depressed by overdrive pacing or by carotid sinus massage ~. 12, that sinus node entrance block may exist in the absence of sinus node exit block 6, and that sinoatrial conduction time and sinus cycle length are directly From the Division of Cardiology, Department of Medicine, Columbia University, New York, New York 10032 and The Arrhythmia Control Unit, The Columba-Presbyterian Medical Center, New York, New York 10032.
