ratios ( decreases in atrial developed tension per decreases in atrial rate ) for alinidine ranged from 1.2 to 2.1 , which were smaller than those of acetylcholine , adenosine and verapamil , suggesting that alinidine has a predominant bradycardic property and induces bradycardia due to a different mechanism from those of other bradycardic agents in the isolated and blood-perfused dog heart .
