ventricular fibrillation/scopolamine

BACKGROUND Low-dose scopolamine increases heart rate variability (HRV) in patients with a prior myocardial infarction (MI). This observation, combined with the evidence that elevated cardiac vagal activity during acute myocardial ischemia is antifibrillatory, has generated the hypothesis that

The incidence of dysrhythmias during the prebypass period of coronary artery surgery has not been accurately reported. Using Holter monitoring of the electrocardiogram, this study was undertaken to determine the incidence of dysrhythmias and ischemia and their relationship to specific events during

The evidence of the predictive value of autonomic markers has generated a growing interest for interventions able to influence autonomic control of heart rate. The hypothesis is that an increase in cardiac vagal activity as detected by an increase in heart rate variability (HRV) or baroreflex

The purpose of conducting cardiovascular safety pharmacology studies is to investigate the pharmacological profiles of new molecular entities (NMEs) and provide data that can be used for optimization of a possible new drug, and help make a selection of NMEs for clinical development. An anaesthetised
