Serial creatine phosphokinase (CPK) isoenzyme determinations were taken in an 8-year-old boy whose being struck by lightning resulted in prolonged cerebral anoxia, inferolateral myocardial infarction and death. All three isoenzyme levels (CPK-MM, CPK-MB, and CPK-BB) were elevated. The CPK-BB isoenzyme level increase was transient, being very high three hours postlightning strike and disappearing at approximately 24 hours.
