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...

Effects Of Fast Pathway Ablation On The Concealment Zone And Electrophysiological Behavior Of AV-Node During Atrial Fibrillation.

Objectives: Dual pathways have a determinant role in the occurrence of atrio nodal tachyarrhythmia (AVNRT). The aim of present study is to determine the role of slow pathway (SP) in the concealment zone and protective role of AV node during atrial fibrillation (AF). Material &Methods: In 7 isolated nodal rabbit preparation zone of concealment and concealed conduction is quantified by Specif...

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...

نقش آدنوزین در اثرات محافظتی سیمواستاتین بر خواص گره دهلیزی- بطنی در مدل فیبریلاسیون دهلیزی ایجاد شده در قلب ایزوله خرگوش

Background: The 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase inhi-bitors (statins) have revolutionized the treatment of hypercholesterolemia. Some evide-nce indicated the role of nodal refractoriness and concealed conduction in anticipating the ventricular rate during atrial fibrillation. Recent evidence has indicated that statins can reduce the incidence of both supraventricular a...

Electrophysiological effects of sotalol--just another beta blocker?

The electrophysiological effects of intravenous sotalol hydrochloride (0.4 mg/kg) were assessed in 24 patients, including 13 with the Wolff-Parkinson-White syndrome, undergoing routine electrophysiological study. Fifteen to 30 minutes after sotalol administration there was a significant increase in sinus cycle length and in sinus node recovery time. There was a small increase in the AH interval...
