Megjegyzések:	The basic hemodynamic, electrophysiological, and pharmacological effects of EGIS-7229(E-7229) were evaluated and compared with those of a pure "Class III" antiarrhythmic drug (GLG-V-13) inconscious rabbits. Both compounds decreased heart rate dose-dependently. Mean arterial blood pressurewas not influenced by E-7229; however, GLG-V-13 produced a significant elevation on this parameter. Leftventricular end-diastolic pressure was gradually increased by E-7229, while GLG-V-13 induced moreconsiderable elevation on that at intermediate doses. QT and QTcb were lengthened by both compounds;however, higher doses of E-7229 resulted in shortening of the prolonged QT and QTcb.Ventricular effectiverefractory period (VERP) was significantly prolonged by either drug studied. Threshold doses to produceQT50%, QTmax, VERP50%, and VERPmax were significantly higher for E-7229 compared with GLG-V-13.Significantly higher doses were required for E-7229 to induce arrhythmias. The safety ratio was comparablefor both of the compounds. E-7229 can exert multiple actions on cardiac ion channels with minimalinfluence on hemodynamic parameters and reduced proarrhytmic profile in our preclinical model.
