The delayed rectifier potassium current (IK) is a major repolarizing current in guinea pig ventricular myocytes. Blockade of IK or other repolarizing currents is of increasing interest for development of antiarrhythmic drugs; however, these interventions may also be proarrhythmic. In the present study, we compared the potential antiarrhythmic properties of(More)
The effects of the triazolobenzodiazepine anxiolytic, alprazolam, on the incidence of ischemia- and reperfusion-induced ventricular arrhythmias was studied in the isolated buffer-perfused rat heart. Administration of alprazolam before and after myocardial ischemia resulted in a dosage-dependent reduction in the incidence and duration of reperfusion-induced(More)
