He underwent further standard resuscitation EXCEPT that we applied the Inspiratory Threshold Device ( ResQPod ) AND applied Dual Sequential Defibrillation (this simply means we applied 2 sets of pads, had 2 defib machines, and defibrillated with both with only a fraction of one second separating each defibrillation.

See this post: Septal STEMI with ST elevation in V1 and V4R, and reciprocal ST depression in V5, V6. She was successfully defibrillated and taken back to the ED. They also sued both EMTs for allegedly not starting chest compressions and defibrillating quickly enough. Also seen in inferior + RV OMI.) There is also STD in V2.

The ECG shows obvious STEMI(+) OMI due to probable proximal LAD occlusion. He required multiple defibrillations within a period of a few hours. This time, the arrhythmia did not spontaneously terminate — but rather degenerated to VFib, requiring defibrillation. The below ECG was recorded. What do you think?

Are Some Cardiologists Really Limited by Strict Adherence to STEMI millimeter criteria? He was found in ventricular fibrillation and defibrillated, then brought to a local ED which does not have a cath lab. This is the response he got: Interventionist: "No STEMI, no cath. It is a STEMI equivalent.

He reports that this chest pain feels different than prior chest pain when he had his STEMI/OMI, but is unable to further describe chest pain. VF was refractory to amiodarone, lidocaine, double-sequential defibrillation, esmolol, etc. Sensitivity was 87% for OMI in our validation study (it was 34% for STEMI criteria).

So there is definitely no STEMI, and the STE is normal. But after reading this blog, you all know that most OMI do NOT meet STEMI criteria. Bedside echo revealed anteroseptal wall motion abnormality at which point I activated a code STEMI. Defibrillated out of v fib in the cath lab. mm in men over age 40.

She was defibrillated and resuscitated. STEMI MINOCA versus NSTEMI MINOCA STEMI occurs in the presence of transmural ischaemia due to transient or persistent complete occlusion of the infarct-related coronary artery. This has resulted in an under-representation of STEMI MINOCA patients in the literature. From Gue at al.

If it is STEMI, it would have to be RBBB with STEMI. Cardioversion/defibrillation. But — one of the causes of Brugada Phenocopy is acute infarction — so I didn’t know how to distinguish between a preexisting Brugada-1 ECG pattern vs a Brugada ECG pattern developing as a result of acute ongoing anterior STEMI.

This is another case written by Pendell Meyers (who is helping to edit the blog and has many great recent posts) Case A 45 year old man was driving to work when he experienced acute onset sharp left sided chest pain with paresthesias of the left arm. A repeat ECG was done: Obvious anterolateral wall STEMI.

When the ICD was finally interrogated, the syncopal events and shocks correlated with two VF events that were defibrillated successfully. Recall that air is a poor conductor of electricity and will, therefore, generate smaller amplitudes on posterior leads (hence why STEMI criteria requires only >0.5

He was resuscitated with chest compressions and defibrillation and 1 mg of epinephrine.

His initial ECG is shown here. He awoke and did well.

Cardiology was consulted and they agreed that the EKG had an atypical morphology for STEMI and did not activate the cath lab.
