TTM following cocaine-induced OHCA unmasks ST-elevations with J-waves and saddleback morphology.
Case Report (n=1)
Case report highlighting the development of J-waves and Brugada-like ECG patterns during targeted temperature management after cardiac arrest.
A 42-year-old man presented after accidental drug overdose complicated by out-of-hospital cardiac arrest. The patient underwent cardiopulmonary resuscitation with successful return of spontaneous circulation and was admitted to the intensive care unit for postcardiac arrest care, which included targeted temperature management (TTM). Urine toxicology screen was positive for cocaine. Initial ECG showed normal sinus rhythm at 84 bpm with incomplete right bundle branch block (RBBB) (figure 1A). During cooling to 33.7°C, ST-segment elevations were noted on the bedside monitor. Follow-up ECG showed sinus bradycardia at 44 bpm with incomplete RBBB, ST-elevations with superimposed J-waves and ‘saddleback appearance’, resembling type …

Bui et al. (2020) conducted a case report in J-wave syndrome following out-of-hospital cardiac arrest and cocaine overdose (n=1). Targeted temperature management (TTM) was evaluated. A 42-year-old man developed ST-elevations with superimposed J-waves and a saddleback appearance during targeted temperature management for out-of-hospital cardiac arrest following cocaine overdose.
