title: Iatrogenic false-positive findings on cardiac scans.
abstract: Two patients subjected to cardiopulmonary resuscitation with chest massage and direct-current cardioversion had positive activity on myocardial scintiscans using radioactive 99mtechnetium pyrophosphate. Possible explanations are offered, and recent reports of false-positive findings on scans due to organic disease, as well as iatrogenic causes, are discussed briefly.
