Implication

May artifactually elevate post-cardioversion 99mTc-PYP uptake; leaves open optimal timing and technique to minimize false positives in humans.

Structured PICO

Does electrical direct current cardioversion cause false positive technetium-99m stannous pyrophosphate myocardial scintigrams in experimental animals?

P
Population
Experimental animals
I
Intervention
Electrical direct current cardioversion (including frequent high energy administration)
O
Outcome
Skeletal muscle damage, myocardial necrosis, and increased technetium-99m stannous pyrophosphate (99mTc-PYP) uptakesurrogate

Direct current cardioversion can cause skeletal and myocardial necrosis leading to false-positive 99mTc-PYP scintigrams, highlighting the need for careful paddle placement.
