Here is his ED ECG: There is obvious infero-posterior STEMI. At cath, he immediately had incessant Torsades de Pointes requiring defibrillation 7 times and requiring placement of a transvenous pacer for overdrive pacing at a rate of 80.

The history, obtained subsequently, is interesting: The patient had been seen at an outside ED 2 days prior and the K was 2.5 Hospital admission had been recommended, but she left that ED against medical advice.

EMS report was that the patient had unknown down time with unwitnessed arrest, found initially in VFib arrest, defibrillated x1 followed by PEA arrest alternating with asystolic arrest during transport. Upon closer inspection, the defibrillator's monitor had assigned a spike for every large T wave as well as every QRS complex.

During observation in the ED the patient had multiple self-terminating runs of Non-Sustained monomorphic Ventricular Tachycardia (NSVT). The minimum effective plasma concentration of flecainide is about 200 ng/mL. This plasma concentration leads to a QRS prolongation of about 10 msec. and Brugada syndrome.
