Key result
Direct current cardioversion for atrial fibrillation induced a rare case of delayed, non-arrhythmic cardiogenic shock with global biventricular dysfunction and multi-organ failure.
Why the study?
Direct current cardioversion is considered relatively safe, but complications can be severe, and delayed presentations of cardiogenic shock post-procedure represent a rare but serious consequence.

Alerts clinicians to rare delayed shock post-cardioversion; leaves open incidence, mechanisms, and prevention strategies.
Direct current cardioversion (DCCV) is an increasingly prevalent procedure to disrupt abnormal rhythms and restore normal sinus rhythm. While considered a relatively safe procedure, complications can be severe. We add to the emerging research surrounding delayed presentations of cardiogenic shock post-DCCV. Together with a review of the current literature, we extrapolate that a combination of post-conversion cardiac shifts, myocardial stunning, and a unique cardioversion stress-induced cardiomyopathy contributed to this occurrence. To our knowledge, this represents one of only a few examples of delayed, non-arrhythmic, cardioversion-induced cardiogenic shock and the first to cause the combination of non-ST elevation myocardial infarction, acute liver injury, and acute kidney injury. Our case adds to the growing body of research highlighting this rare, but serious consequence of direct current cardioversion.

Freedman et al. (2022) conducted a case report in Atrial fibrillation with rapid ventricular response (n=1). Direct current cardioversion (DCCV) was evaluated on Development of cardiogenic shock and multi-organ injury. Direct current cardioversion for atrial fibrillation induced a rare case of delayed, non-arrhythmic cardiogenic shock with global biventricular dysfunction and multi-organ failure.
