There is sinus bradycardia with one PVC. This is a troponin I level that is almost exclusively seen in STEMI. So this is either a case of MINOCA, or a case of Type II STEMI. If the arrest had another etiology (such as old scar), and the ST elevation is due to severe shock, then it is a type II STEMI.

Here is his ED ECG: There is obvious infero-posterior STEMI. What are you worried about in addition to his STEMI? There is also bradycardia. Bradycardia puts patients at risk for "pause-dependent" Torsades de Pointes. Bradycardia puts patients at risk for "pause-dependent" Torsades de Pointes.

Still, an ECG was obtained at 0649hrs: (Digitized by PM Cardio) McLaren: The patient has a high pretest probability based on age, risk factors and symptoms. STEMI criteria are only 43% sensitive for OMI. Beware confusing the diagnosis of posterior STEMI by using posterior leads.

--Genetic testing could be helpful to confirm the diagnosis and allow for screening of other at-risk family members. --EP EP study to further risk stratify her is recommended, with ICD placement depending on the results. Conclusion of this paper: Fever is a great risk factor for arrhythmia events in Brugada Syndrome patients.

They recorded this ECG: Obvious inferior STEMI/OMI What else? There is also STE in V1 which is diagnostic of right ventricular OMI in this situation , and partly explains the syncope and hypotension (along with the bradycardia). Medics recorded a BP of 79/52 with pulse of 47. As I wrote in that Nov. The cardiac cath was "normal".
