BACKGROUND The mortality rate among patients with coronary artery disease, abnormal ventricular function, and unsustained ventricular tachycardia is high. The usefulness of electrophysiologic testing for risk stratification in these patients is unclear. METHODS We performed electrophysiologic testing in patients who had coronary artery disease, a left ventricular ejection fraction of 40 perce...

Background. Wolff, Parkinson and White (I) in 1930 reported an electrophysiologic syndrome based on their observation of 11 "healthy young" people who had "bundle branch block with short PR interval" and who were "prone to paroxysmal tachycardia." However, substantial progress in understanding the pathophysiology and in devising therapy for the various complex arrhythmias in patients with this ...

Objective(s):In this study, we aimed at evaluation of electrophysiological and histopathalogical characteristics of statin-induced muscle injury as well as clinical features of patients who develop this condition in terms of frequency and pattern of evolution. Materials and Methods: Forty patients (age 39-74 years) including 25 subjects with type 2 diabetes mellitus, 9 with cardiovascular disea...

background: potassium, as an extracellular ion, plays an important role in the electrophysiologic function of the myocardium and any change in extracellular concentration of this ion might have a marked impression upon myocyte electrophysiologic gain. high serum potassium levels are thought to impair pulse conduction in purkinje fibers and ventricles more than that in the atrioventricular (av) ...
