Technetium - 99 m Stannous Pyrophosphate Myocardial Scintigraphy after Cardiopulmonary Resuscitation with Cardioversion RICHARD
نویسندگان
چکیده
Thirty consecutive patients underwent technetium-99m stannous pyrophosphate myocardial scintigraphy 48-72 hours after successful cardiopulmonary resuscitation and direct current cardioversion. Five patients with transmural myocardial infarctions by ECG and enzyme determinations were correctly identified by scintigraphy. Myocardial scans were positive in five of nine patients with nontransmural infarction. Of 16 patients without evidence of myocardial infarction, only two (13%) had false-positive myocardial scans. The overall accuracy of imaging in this series was 80%. We conclude that false-positive scans after cardiopul-

متن کاملCardioversion and "false positive" technetium-99m stannous pyrophosphate myocardial scintigrams.
The present studies performed in experimental animals demonstrate that electrical direct current cardioversion can produce skeletal muscle damage and increased technetium-99m stannous pyrophosphate (99mTc-PYP) uptake; in experimental animals the electrically damaged skeletal muscle shows necrosis with extensive calcium deposition. In addition, the frequent administration of high energy cardiove...

In a select series of 46 patients studied by serial myocardial scintigraphy, 19 (41%) retained persistent, usually low grade (2+) positive technetium-99m stannous pyrophosphate ('9mTc-PYP) myocardial scintigrams for at least 3 months after acute myocardial infarction. The one major difference between patients with positive and negative postinfarct 59mTc-PYP myocardial scintigrams was a more sym...
