ECG is consistent with severe hypokalemia and/or hypomagnesemia causing prolonged QT (QU) at high risk of Torsades (which is polymorphic ventricular tachycardia in the setting of a long QT interval). The patient was admitted to the ICU for close monitoring and electrolyte repletion and had an uneventful hospital course.

The only time you see this without ischemia is when there is an abnormal QRS, such as LVH, LBBB, LV aneurysm (old MI with persistent STE) or WPW." The patient was managed in the ICU and had serial troponins. Here is the patient's troponin I profile: These were interpreted as due to demand ischemia, or type II MI. First was 2.9

After initiating treatment for hyperkalemia, repeat ECG showed resolution of Brugada pattern: The ECG shows sinus tachycardia. He was admitted to the ICU and transferred emergently to a facility where he could undergo emergent dialysis as a part of further evaluation and management. A Very Wide Complex Tachycardia.
