ST-segment elevation with elective DC cardioversion
PK Chun, JE Davia and DJ Donohue
Elective direct-current cardioversion was performed in three patients with
atrial fibrillation. Transient ST-segment elevation on monitored leads,
lasting seconds, was recorded after cardioversion in all three patients.
LDH, CPK isoenzymes, and myocardial scintigraphy did not reveal myocardial
damage. Elective cardioversion should be performed with caution, for the
potential for cardiac damage cannot be ignored.
