1. 1. Second degree atrioventricular (A-V) block was induced by infusion of potassium in 76 of 78 experiments in dogs. 2. 2. The variations of A-V block, some rarely if ever observed in man, are described and the role of A-V alternans and concealed conduction in the appearance of the bizarre variants of A-V block is suggested. 3. 3. Interruption of the vagus by vagotomy or administration of sufficient amounts of atropine was without any influence on the potassium-induced A-V block.
