[The effects of succinylcholine on heart rate and rhythm in infants].

The authors examined the possible variations of cardiac activity in 91 infants aged between a few days and six months in order to study the changes following administration of succinylcholine during general anaesthesia. No variations in rhythm and/or heart rate occurred, not even in those children to whom atropine had not been injected intravenously before succinylcholine.
