Electrical potential distribution surrounding the atria during depolarization and repolarization in the dog.
The potential distribution at the atrial surface during depolarization and repolarization was studied in intact dogs. A preparation was developed by implanting 30 to 40 miniature electrodes permanently on each atrium to record unipolar electrograms in the intact animal. Heart block was created to dissociate atrial and ventricular activity. The electrograms were recorded on magnetic tape and atr...
متن کاملBody Surface Potential Mapping in Rats with Experimental Pulmonary Hypertension
Body surface potential mapping (BSPM) was performed in female rats with pulmonary arterial hypertension (PAH) induced by a single subcutaneous injection monocrotaline (60 mg/kg body wt). Analysis of data was produced by equipotential momentous maps during ventricle depolarization. In rats with monocrotaline-induced PAH was confirmed hypertrophy of the right ventricle. It is reflected on equipot...
متن کاملBody surface distribution of electrical potential during atrial depolarization and repolarization.
Limited information is available documenting body surface isopotential distributions during atrial excitation and recovery. To expand the current data base, body surface isopotential maps from 40 normal subjects were examined. Data were acquired at a gain of 10,000 and isopotential distributions constructed at 2-msec intervals from the onset of the P wave to the onset of the QRS complex. During...
متن کاملElectrocardiographic identification of abnormal ventricular depolarization and repolarization in patients with idiopathic ventricular fibrillation.
OBJECTIVES We sought to gain more insight into the arrhythmogenic etiology of idiopathic ventricular fibrillation (VF) by assessing ventricular depolarization and repolarization properties by means of various electrocardiographic (ECG) techniques. BACKGROUND Idiopathic VF occurs in the absence of demonstrable structural heart disease. Abnormalities in ventricular depolarization or repolarizat...
متن کاملAntiarrhythmic and Electrophysiologic Effects of Flecainide on Acutely Induced Atrial Fibrillation in Healthy Horses
BACKGROUND Only few pharmacologic compounds have been validated for treatment of atrial fibrillation (AF) in horses. Studies investigating the utility and safety of flecainide to treat AF in horses have produced conflicting results, and the antiarrhythmic mechanisms of flecainide are not fully understood. OBJECTIVES To study the potential of flecainide to terminate acutely induced AF of short...
