OBJECTIVE Impairment of the baroreceptor reflex activity reflects an alteration of the autonomous regulation of the cardiovascular system and has proven to predict fatal outcome in patients after acute myocardial infarction. The following study was performed to analyse the baroreceptor sensitivity, heart rate variability and blood pressure variability in(More)
BACKGROUND Atrial fibrillation (AF) occurs in 20-40% of patients after open heart surgery and leads to an increased morbidity and prolonged hospital stay. Earlier studies have demonstrated that depressed baroreflex function predicts mortality and major arrhythmic events in patients surviving myocardial infarction. Cardiac surgery per se leads to decreased(More)
The study was performed on 84 healthy volunteers (33 women, 52 men) of age 20-71 years with no history of the circulatory or gastrointestinal system disease. The gastric myoelectrical activity (EGG) was recorded with the cutaneous electrodes--electrogastrography Synectics (Sweden). The activity of the cardiac autonomic nervous system was measured by HRV(More)
Baroreflex sensitivity, heart rate and blood pressure variability have been proven to predict fatal outcome in patients after acute myocardial infarction. This study aims at investigating the time dependent alterations in cardiovascular control to find new predictive parameters for arrhythmic events after surgery. 25 male patients with coronary heart(More)
Post-transfusion hepatitis was studied prospectively in 1,476 patients undergoing open-heart surgery between 1985 and 1988. Thirty-three (2.2%) patients suffered from post-transfusion hepatitis. Acute post-transfusion hepatitis was attributed to hepatitis B in one case and to hepatitis C in ten patients (0.7%). Four additional patients had preexisting(More)
UNLABELLED TENS became widely accepted method of treatment pain syndromes in clinical practice. Lately has been shown that its affects also gastrointestinal tract by releasing NANC neurotransmitter VIP. The aim of this study was to evaluate the effects of TENS on gastric myoelectric activities measured by electrogastrography (EGG). Eighteen healthy men(More)
