Why the study?
Current guidelines list direct current cardioversion as a cause of myocardial injury, prompting evaluation of whether it induces injury measured by serial high-sensitivity troponins.
Does elective external DC cardioversion cause myocardial injury in patients with atrial fibrillation?
Does elective external DC cardioversion cause myocardial injury in patients with atrial fibrillation?
Elective DC cardioversion for atrial fibrillation rarely causes significant myocardial injury, suggesting that marked troponin elevations post-cardioversion should prompt investigation for other causes.
No takes yet. Share an insight, caveat, or question.
Small troponin rises post-elective DCCV rarely meet injury criteria; leaves open whether post-procedure testing warrants routine investigation in stable AF.
Lobo et al. (2022) studied this question.
