Antiarrhythmic and electrophysiologic effects of ibutilide in a chronic canine model of atrial flutter.

abstract：:Monophasic action potentials (MAPs) were utilized to examine the basis for cesium-induced arrhythmia in the dog. Cesium chloride (1 mmol/kg i.v.) produced an immediate prolongation of MAP (250 +/- 11 to 396 +/- 34 ms, p less than 0.05). Coupled premature ventricular beats (345 +/- 46 ms) and polymorphic ventricular ta...
