Key result
Electrical cardioversion did not cause myocardial damage, with cardiac troponin T rapid assays testing positive in 0% of patients up to 24 hours post-procedure.
Why the study?

Supports safe cardioversion without troponin monitoring in SVT; leaves open randomized confirmation in diverse populations.
Observational (n=40)
Does electrical cardioversion cause myocardial injury as measured by cardiac troponin T and CPK-MB in patients with supraventricular tachyarrhythmias?
Electrical cardioversion does not cause myocardial damage as evidenced by the absence of troponin T and CPK-MB elevations, despite increases in total CPK.
Alvarez et al. (1997) conducted an observational in Supraventricular tachyarrhythmias (n=40). Electrical cardioversion was evaluated on Cardiac troponin T test positivity at 6, 12, and 24 hours. Electrical cardioversion did not cause myocardial damage, with cardiac troponin T rapid assays testing positive in 0% of patients up to 24 hours post-procedure.
