Cystic Tumor of the Atrioventricular Node Causing Rapid-Onset and Reversible Complete Heart Block

JACC: Case Reports, 2023
Cystic tumors of the atrioventricular node are rare primary cardiac neoplasms, frequently reported as a postmortem diagnosis during autopsy. Despite their small size, they can present with complete heart block or sudden cardiac death.

Potential usage of cardioneuroablation in vagally mediated functional atrioventricular block

SAGE Open Medicine, 2019
An increase in parasympathetic tone may be the main cause of some transient or permanent atrioventricular block cases. Some of these patients, defined as vagally mediated functional atrioventricular block, may be severely symptomatic and refractory to ...

Analysis of Arrhythmogenic Profile in a Canine Model of Chronic Atrioventricular Block by Comparing In Vitro Effects of the Class III Antiarrhythmic Drug Nifekalant on the Ventricular Action Potential Indices Between Normal Heart and Atrioventricular Block Heart

Journal of Pharmacological Sciences, 2007
The chronic atrioventricular block dog is a useful model for predicting the future onset of drug-induced long QT syndrome in clinical practice. To better understand the arrhythmogenic profile of this model, we recorded the action potentials of the ...
