Ionic basis of a differential effect of adenosine on refractoriness in rabbit AV nodal and atrial isolated myocytes [PDF]

, 1999
Methods: The whole cell patch clamp technique was used to record action potentials and ion currents in AV nodal and left atrial myocytes isolated enzymatically from rabbit hearts.

Evidence that conflict regarding size of haemodynamic response to interventricular delay optimization of cardiac resynchronization therapy may arise from differences in how atrioventricular delay is kept constant. [PDF]

, 2014
Aims: Whether adjusting interventricular (VV) delay changes haemodynamic efficacy of cardiac resynchronization therapy (CRT) is controversial, with conflicting results.

Transient complete atrioventricular block and ST-segment elevation induced by coronary vasospasm due to iatrogenic hyperkalemia: a case report

Journal of Medical Case Reports, 2021
Background Hyperkalemia and acute coronary syndrome are not only all responsible for syncope related to complete atrioventricular block, but also share parts of electrocardiogram manifestations. Additionally, they influence each other.

Late recovery of sinus rhythm following perioperative complete atrioventricular block in a child with congenitally corrected transposition

Annals of Pediatric Cardiology, 2018
We report a patient with l-transposition of the great arteries who developed perioperative complete atrioventricular block at 5 years of age in conjunction with a modified double-switch operation, but had unexpected late recovery of normal sinus rhythm ...

Advanced ablation strategies for management of post-surgical atrial arrhythmias. [PDF]

, 2013
Post-surgical arrhythmias include a wide range of arrhythmias occurring late after cardiac surgery and represent a complex substrate for catheter ablation either because of extended scar and remodeling or because of limited access to the area of interest.

Impact of untreated hypothyroidism on the cardiac conduction system: A case report and review of pathophysiology [PDF]

Romanian Journal of Medical Practice
Background. Third-degree atrioventricular (AV) block, also referred as complete heart block, results from the complete disruption of impulse transmission between the atria and ventricles, leading to desynchronized electrical activity.
