Unfortunately, this was not recognized at this time. I believe it was this point when hyperkalemia was first suspected.

This patient is actively dying from a left main coronary artery OMI and cardiac arrest from VT/VF or PEA is imminent! Complete LMCA occlusion is associated with clinical shock and/or cardiac arrest. The arterial blood gas showed a lactic acidosis with a lactate level of 17mmol/L.

Hyperkalemia causes peaked T waves and the "killer B's of hyperkalemia", including bradycardia, broad QRS complexes, blocks of the AV node and bundle branches, Brugada morphology, and otherwise bizarre morphology including sine wave. Steve, what do you think of this ECG in this Cardiac Arrest Patient?" With a twist.

There is sinus bradycardia with one PVC. There is "Shark Fin morphology" I saw this and thought for certain that this was going to be an LAD or left main occlusion as etiology of arrest, and etiology of profound ST Elevation in I, II, aVL, and V3-V6, and ST depression in III, V1 and V2. She then had a 12-lead: What do you think?

This ECG pattern may be diagnostic of B rugada S yndrome IF seen in association with: i ) a history of cardiac arrest; polymorphic VT; or of non-vagal syncope; and / or ii ) a positive family history of sudden death at an early age; and / or iii ) a similar ECG in relatives. Bradycardia. Acute febrile illness. Hypothermia.
