Effects of atropine on cardiac rate and rhythm in dogs.

摘要: Changes in cardiac rate and rhythm were determined atropinized dogs prior to, during, after anesthetic induction with thiamylal sodium maintenance 1% halothane 50% nitrous oxide oxygen. The incidence of dysrhythmias sinus tachycardia was significantly higher to given atropine, compared not atropinized. Second-degree atrioventricular block the most frequent dysrhythmia dogs. Most detected during early periods. common these periods unifocal ventricular premature depolarizations bigeminy.
