Reciprocal rhythm of ventricular origin during atrial fibrillation with complete AV block.

نویسنده

  • L Schamroth
چکیده

A case of reciprocal rhythm of ventricular origin associated with atrial fibrillation and complete AV block is described. This manifestation shows that an atrial bridge is not an essential link in the reciprocal mechanism, and that the reciprocal mechanism is effected through the presence of an upper common AV nodal pathway.

Modulation of extracellular atrioventricular node field potential pattern and ventricular rhythm by morphine in experimental atrial fibrillation in isolated rabbit heart

Introduction: Endorphins are produced by cardiomyocytes, and exert different effects on the heart. The aim of the present study is to assess morphine effects on extracellular atrioventricular (AV) node field potential pattern and ventricular rhythm of isolated rabbit heart during experimental atrial fibrillation (AF). Methods: Effects of different concentrations of morphine (10, 20, 50 and 1...

New manifestations of electrophysiological remodeling of heart during experimental model of atrial fibrillation in cirrhotic rat isolated heart

Introduction: The present study is aimed to evaluate electrophysiological remodeling of atrioventricular (AV) node and ventricular conduction during experimental atrial fibrillation (AF) model in isolated heart of cirrhotic rats. Methods: Cirrhosis-induced electrophysiological remodeling was evaluated in 24 isolated retrogradely perfused rat hearts in 2 groups (control and cirrhotic). Cirrho...

Resolution of AV block after ablation for atrial fibrillation.

We report a case with complete atrioventricular block (AVB) present both during sinus rhythm and with atrial fibrillation (AF). He had declined pacemaker placement and opted for ablation for the symptomatic AF. He underwent staged hybrid approach with video-assisted thoracoscopic surgical maze (VATS) followed by endocardial ablation. VATS included ganglionic plexi cauterization. One month after...

Protective effects of simvastatin on atrioventricular node during simulated experimental atrial fibrillation in vitro

Introduction: Recent evidence has indicated that statins can reduce the incidence of both supraventricular and ventricular arrhythmias with various mechanisms. The primary goal of the present study was to determine direct protective role of simvastatin in modifying concealed conduction and the zone of concealment in a simulated model of atrial fibrillation (AF) in an isolated atrioventricula...

Acute direct effects of cyclosporine on extracellular field potential of isolated rabbit AV node during experimental atrial fibrillation

Introduction: Previous studies have indicated a relationship between MPTP pore and AV nodal rate-dependent properties. The aim of present study was to determine acute direct effects of cyclosporine on extracellular field potential of isolated rabbit AV node during experimental atrial fibrillation. Methods: In one group of male New Zealand rabbits (1.5-2.5 kg) cumulative concentrations of cyc...
