A patient with severe angina pectoris and congestive heart failure had chronic Wenckebach-type atrioventricular block and episodes of syncope. Atropine abolished the block and prevented the Stokes-Adams attacks. Carotid sinus pressure, digoxin, and exercise increased the block; atropine prevented these effects.
