No ventricular arrhythmias occurred during competitive pacing between the sinus node and an artificial pacemaker in 20 normal dogs. After intravenous quinidine serious ventricular arrhythmias triggered by pacemaker stimuli falling in the vulnerable period of sinus beats were noted in 14 of the same animals. Theoretical considerations and possible clinical implications of these phenomena are discussed.

    Zatebradine, a potent bradycardic agent, is believed to act selectively at the sinoatrial node. The selectivity of such a property relative to various electrophysiologic classes of action is not well defined. To characterize the electrophysiologic properties of zatebradine, the corrected sinus...
