It was witnessed, and CPR was performed by trained individuals. She arrived in the ED 37 minutes after 911 was called, with continuing CPR. Here is an article I wrote: Updates on the ECG in ACS. Was this: 1) ACS with ischemia and spontaneous reperfusion? Updates on the Electrocardiogram in Acute Coronary Syndromes.

However, vertical flow can result in myocardial injury secondary to coronary artery spasm. This is supplied via alternating current (AC), increasing the risk of titanic contraction of skeletal muscle, leading to kids holding on to the electrical power source. AC and DC shocks may result in different injury patterns.

He underwent immediate CPR, was found to be in ventricular fibrillation, and was successfully resuscitated. He underwent coronary stenting (uncertain which artery). See explanation below. The patient went home and, in front of his wife, he collapsed. I do not have the post-resuscitation ECG. Did the ECG offer unseen hints?

CPR was initiated immediately. If this is ACS with Aslanger's pattern , the ST depression vector of subendocardial ischemia (due to simultaneous 3 vessel or left main ACS) is directed toward lead II (inferior and lateral). It was reportedly a PEA arrest; there was no recorded V Fib and no defibrillation.

Medics found her apneic and pulseless, began CPR, and she was found to be in asystole. Rather it is due to coronary insufficiency due to a tight left main or 3-vessel disease with inadequate coronary flow. A middle-age woman with h/o hypertension was found down by her husband.

He underwent CPR and then was shocked out of VF. ST depression maximal in V1-V4, in the context of ACS symptoms and unexplained by QRS abnormality or tachydysrhythmia, should be considered posterior OMI until proven otherwise. Today's patient is high-risk ( ie, in a high "prevalence" group for having an acute coronary event ).

CPR was initiated and she subsequently entered into V-Fib storm. ACS can be a very dynamic process. For example, a coronary plaque ruptures: the vessel can undergo occlusion, spontaneous reperfusion, maybe reocclusion, again reperfusion, etc. Shortly after this ECG she suddenly went unresponsive and into V-Fib.

Data that do not establish neurological risk stratification in the first 6 hours after CA include the patient’s age, duration of CPR, seizure activity, serum lactate level or pH, Glasgow motor subscore in patients who received NMB or sedation, pupillary function in patients who received atropine, and optic nerve sheath diameter (95.3%, 20/21).

In total, he received approximately 40 minutes of CPR and 7 defibrillation attempts. Coronary spasm causing massive current of injury with shark fin ECG. I would not expect ST-E to vanish in four beats with dissolving thrombus (also we know that the coronaries were clean). I suspect LAD or LM.

He underwent CPR, and regained a pulse after epinephrine, with an organized narrow complex rhythm at 140, but still with severe shock. And so it is wise to look at the coronary arteries. This ECG certainly looks like myocarditis, and was due to myocarditis, but missing acute coronary occlusion is not acceptable.

The arterial pressure waveform is transduced using the coronary catheter. Normally, the diameter of the coronary artery ostium is much greater than the diameter of the catheter so that catheter engagement does not significantly impair antegrade coronary perfusion. Here is the ECG and arterial waveform during RCA angiography.
