There was concern that the rhythm might represent ventricular tachycardia, so lidocaine was given and one attempt at cardioversion was performed. A woman in her 50s with dyspnea and bradycardia A patient with cardiac arrest, ROSC, and right bundle branch block (RBBB). HyperKalemia with Cardiac Arrest.

But cardiac arrest is a period of near zero flow in the coronary arteries and causes SEVERE ischemia. After cardiac arrest, I ALWAYS wait 15 minutes after an ECG like this and record another. See these related cases: Cardiac arrest, defibrillated, diffuse ST depression and ST Elevation in aVR.

A small proportion of patients with STEMI treated via primary PCI experienced late ventricular tachycardia (VT) or ventricular fibrillation (VF), occurring one or more days following the procedure, but late VT or VF with cardiac arrest occurred rarely, especially among patients with uncomplicated STEMI, according to a study published in JAMA Network (..)

The ECG in Figure-1 — was obtained from a middle-aged man who presented to the ED ( E mergency D epartment ) in cardiac arrest. Prompt cath is therefore advised if the post-ROSC shows an acute STEMI. Continuing with assessment of ECG #1 in Figure-2: The rhythm is sinus tachycardia at ~110/minute.

This certainly looks like an anterior STEMI (proximal LAD occlusion), with STE and hyperacute T-waves (HATW) in V2-V6 and I and aVL. How do you explain the anterior STEMI(+)OMI immediately after ROSC evolving into posterior OMI 30 minutes later? This caused a type 2 anterior STEMI.

He had multiple cardiac arrests with ROSC regained each time. Then there is loss of pulses with continued narrow complex on the monitor ("PEA arrest") Learning Points: Sudden witnessed Cardiac Arrest due to ACS is almost always due to dysrhythmia. This patient arrested shortly after hospital arrival.

In a series of 18 patients with COVID and ST elevation, 8 were diagnosed with STEMI, 6 of whom had an angiogram and it showed obstructive coronary disease. 12 All STEMI patients had very high cTn typical of STEMI (cTnT > 1.0 Elevated troponin does not, however, guide any treatment strategies to minimize myocardial injury.
