CARDIAC ARRHYTHMIAS OCCURRING DURING HALOTHANE ANAESTHESIA IN CATS

摘要

SUMMARYThe incidence of cardiac arrhythmias in cats during halothane anaesthesia is high, and the arrhythmias observed during thirty-seven periods of anaesthesia have been classified into four types. The effect of the concentration of halothane, the blood pressure, the arterial blood gases and sensory stimulation on the occurrence of the ventricular extrasystoles with contradirectional interference are described. It is suggested that, under certain conditions, halothane may produce cardiac arrythmias in cats through a direct action on the myocardium.
