Creatine phosphokinase following cardioversion.
Serial estimations of total serum creatine phosphokinase (CPK) have been performed before and during 18-51 hours after cardioversion of supraventricular tachyarrhythmias in 12 patients without acute myocardial infarction (AMI). The maximal CPK rise was 78 mU/ml (110%) and the CPK did not exceed the upper normal limit (130 mU/ml) in more than two patients (149 respectively 156 mU/ml). The CPK rise we have observed in a series of AMI patients varied between 101 (133%) and 2 260 mU/ml (3 780%), mean 900 mU/ml (1 184%). Therefore, cardioversion performed as described seldom seems to interfere with diagnosing AMI by serial estimations of serum CPK during the next 24 hours.
