arrhythmias in dogs (part 9)

Pentobarbital anesthetized group: Under pentobarbital anesthesia, which increased the heart rate to 180 beats/min (n=77), QTc prolongation was blunted by the class III drugs compared with that under halothane anesthesia. Immediately after coronary reperfusion, 26 of 39 (67%) dogs fibrillated in the control group. Class III drugs again showed QTc prolongation, but to a lesser degree than in the halothane group, and bradycardia, and they did not alter the number of PVCs during the 30 mins of coronary occlusion. MS-551 suppressed VF in this group as well as in the group with halothane, but D-sotalol and KCB 328 suppressed the occurrence of VF only in the pentobarbital anesthetized dogs. Only sematilide and dofetilide did not suppress VF in either the halothane or the pentobarbital group of dogs. During the 30 mins of drug administration before applying coronary ligation, no drugs induced ventricular arrhythmias in these pentobarbital anesthetized beagles. In dogs with ‘old’ myocardial infarction of more than one week, there were always some PVCs in the 24 h ECG recordings, but the number of PVCs increased after oral class III drugs.
