To study recurrent ventricular tachycardia in the late phase or myocardial infarction (MI), transmural anteroapical infarcts were created by ligation of the left anterior descending (LAD) coronary artery in 25 dogs. Twenty dogs survived LAD ligation and underwent an open-chest electrophysiologic study an average of 20 days after MI. Programmed electrical stimulation was carried out using the ex...

procainamide on the electrophysiologic properties of the canine ventricular conducting system. J Pharmacol Exp Ther 185: 438, 1973 15. Singh BN, Vaughn-Williams EM: Effect of altering potassium concentrations on the action of lidocaine and diphenylhydantoin on rabbit atrial and ventricular muscle. Circ Res 29: 286, 1971 16.

The electrophysiologic effects of intravenous lorcainide (2.2 mg/kg) in 10 patients were compared with the electrophysiologic effects of oral lorcainide (mean dose 400 mg/day for 8 days) in 11 patients, all with recurrent ventricular tachycardia that could be induced with programmed stimulation. Intravenous and oral lorcainide resulted in similar prolongation of the QRS, QT, and HV intervals, b...
The term "Electrophysiological remodeling" defines the changes of atrial electrophysiologic properties taking place in atrial myocites during atrial fibrillation and/or following periods of sustained atrial fibrillation (AF). Early research was prompted by clinical observations: many patients were seen to get through increasingly frequent and longer paroxisms of AF to persistent AF, until chron...
The authors carried out genetic analyses and visual electrophysiologic evaluations in six asymptomatic sons and daughters of patients with symptomatic cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL). Three subjects showed Notch3 Cys146Tyr missense mutation and a dysfunction of the outer, middle, and innermost retinal layers, with normal neura...
OBJECTIVES The purpose of this study was to analyze the electrophysiologic remodeling of the atrophic left ventricle (LV) in right ventricular (RV) failure (RVF) after RV pressure overload. BACKGROUND The LV in pressure-induced RVF develops dysfunction, reduction in mass, and altered gene expression, due to atrophic remodeling. LV atrophy is associated with electrophysiologic remodeling. ME...
