Effects of procainamide on intra-arterial electrograms during atrial fibrillation: implication for detection algorithms

The effects of antiarrhythmic drugs on electrograms have implications for arrhythmiadetection algorithms in implantable antitachycardia devices. Filtered and unfiltered intra-atrial electrograms were analyzed in eight patients who received procainamide (50 mg/min iv, up to 1000 mg) during 11 episodes of atrial fibrillation. Continuous recordings were made before, during, and after the infusion....

An Algorithm for the Detection and Classification of Atrial Fibrillation from Intra-atrial Electrograms

Reliable detection of atrial fibrillation from intra-atrial signals is a central task in the development of implantable atrial defibrillators. Atrial rate (AR) and the amplitude probability density function (APDF) are normally used as parameters for discriminating between normal sinus rhythm (NSR) and atrial fibrillation (AF). We hereby propose a new peak-detection scheme based on threshold cro...

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...

Characterization of Electrograms from Multipolar Diagnostic Catheters during Atrial Fibrillation

Atrial fibrillation (AF) is the most common arrhythmia in USA with more than 2.3 million people affected annually. Catheter ablation procedure is a method for treatment of AF, which involves 3D electroanatomic mapping of the patient's left atrium (LA) by maneuvering a conventional multipolar diagnostic catheter (MPDC) along the LA endocardial surface after which pulmonary vein (PV) isolation is...
