In any case, there is bradycardia. It was a PEA or bradyasystolic arrest , not a shockable rhythm. Although most cardiac arrest from MI is due to ventricular fibrillation, some is due to high grade AV block, and so this could indeed be due to large acute STEMI. No shock was ever delivered. Sixth: Severe shock (e.g.,

Despite the clinical context, Cardiology was consulted due to concerns for a "STEMI". 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. With a twist.

If it is STEMI, it would have to be RBBB with STEMI. 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.

The provider contacted cardiology to discuss the case, but cardiology "didn't think it was a STEMI, didn't think he needed emergent cath." About two hours after admission, he suffered a cardiac arrest (whether it was VF/VT or PEA is not available) and expired. The whole paradigm is literally called "STEMI" vs. "NSTEMI."

2) The STE in V1 and V2 has an R'-wave and downsloping ST segments, very atypical for STEMI. Cardiology was consulted and they agreed that the EKG had an atypical morphology for STEMI and did not activate the cath lab. Smith comment: 1) Brugada ECG may have ST shifts in limb leads as well as precordial leads. Bicarb 20, Lactate 4.2,

Theres sinus bradycardia, borderline PR interval, narrow QRS; normal axis/R wave progression; low precordial voltages, and subtle peaked T waves (most obvious in V2, but all T waves are symmetric with a narrow base). Theres no prior ECG to compare - but the bradycardia, prolonged PR and peaked T waves could all be from hyperkalemia.

Further history later: This patient personally has no further high risk features (syncope / presyncope), but her mother had sudden cardiac arrest in sleep. Regardless of further evaluation, she should avoid bradycardia, AV nodal blockers, Na channel blockers, and fevers. --If Syncope and ST Segment Elevation.

A 12-lead was recorded, showing "STEMI," but is unavailable. The patient was unconscious BEFORE the cardiac arrest, at the same time that she had strong pulses. Therefore, cardiac arrest is NOT the etiology of the coma. She was BVM ventilated and suctioned. Shortly thereafter, pulses were lost.

ECG met STEMI criteria and was labeled STEMI by computer interpretation. This ECG shows a sinus bradycardia with a normal conduction pattern (normal PR, normal QRS, and normal QTc), normal axis, normal R-wave progression, normal voltages. Hypothermia can also produce bradycardia and J waves, with a pseudo-STEMI pattern.
