Electrophysiological testing was performed in 100 consecutive patients with spontaneous asymptomatic nonsustained ventricular tachycardia, chronic coronary artery disease, and ejection fraction of less than 40%. Fifty-seven patients without inducible sustained ventricular arrhythmias were discharged on no antiarrhythmic therapy. Sustained monomorphic ventricular tachycardia was induced in 37 pa...

The incidence of arrhythmias during isometric sustained handgrip exercise and during dynamic graded bicycle exercise was compared in a group of 45 patients with various forms of heart disease on no antiarrhythmic therapy. Atrial arrhythmias were equally common during handgrip and bicycle exercise but ventricular arrhythmias were more frequent during handgrip exercise. Of the 45 patients, 38 per...

background there is the controversy concerning the main component of tobacco, which is responsible for its arrhythmogenesis. in addition, there is the lack of adequate information about the influence of combination of black tea and nicotine on heart rhythm. objectives this study aimed to examine whether pretreatment with black tea and nicotine could modulate the susceptibility to lethal ventric...

Electrocardiograms of 70 patients with chronic airway obstruction were examined from 148 consecutive admissions for acute respiratory failure. Forty-seven percent of the patients had major sopraventricular or ventricular arrhythmias. These arrhythmias were documented on 36 percent of bospital mbidwns. Supraventricular arrhythmias were slihtiy more common than ventricular arrhythmias, the most f...

BACKGROUND The development of arrhythmias during placement of a pulmonary artery catheter (PAC) is common. AIMS This study was designed to examine factors influencing development of ventricular arrhythmias in adult patients undergoing cardiovascular operations during the catheter placement. SETTINGS AND DESIGNS Prospective, observational, cohort study. METHODS We prospectively studied 174...

This study intended to assess the efficacy of acute administration of natural honey on cardiac arrhythmias and infarct size when it is used during the normothermic ischemia in isolated rat heart. During 30 min of regional normothermic ischemia followed by 120 min of reperfusion, the isolated hearts were perfused by a modified drug free Krebs-Henseleit solution (control) or the solution containi...
