Although one may have all kinds of ischemic findings as a result of cardiac arrest (rather than cause of cardiac arrest), this degree of ST elevation and HATW is all but diagnostic of acute proximal LAD occlusion. This prompted cath lab activation. On arrival to the ED, this ECG was recorded: What do you think?

Bedside cardiac ultrasound showed moderately decreased LV function. CT of the chest showed no pulmonary embolism but bibasilar infiltrates. See this post: How a pause can cause cardiac arrest 2. She was intubated. She had an ECG recorded: This is left bundle branch block (LBBB), with appropriate proportional discordance.

She was unable to be defibrillated but was cannulated and placed on ECMO in our Emergency Department (ECLS - extracorporeal life support). After good ECMO flow was established, she was successfully defibrillated. Here is a case of ECMO defibrillation with near shark fin that was due to proximal LAD occlusion. The K was normal.

She was defibrillated and resuscitated. It is apparently fortunate that she had a cardiac arrest; otherwise, her ECG would have been ignored. Then they did an MRI: Patient underwent cardiac MRI on 10/4 that showed mildly reduced BiV systolic function. I need to innoculate you against the subsequent opinions below.

Implantable Cardioverter-Defibrillator (ICD) to help manage dangerous heart rhythms. Blood Clots: An enlarged heart is more prone to developing blood clots, which can lead to stroke or pulmonary embolism.

It was reportedly a PEA arrest; there was no recorded V Fib and no defibrillation. The morphology of V2-V4 is very specific in my experience for acute right heart strain (which has many potential etiologies, but none more common and important in EM than acute pulmonary embolism). CPR was initiated immediately. This is a quiz.

Background:Epicardial patch defibrillators (EPDs) were commonly implanted in the 1990s for secondary prevention of sudden cardiac death. This case highlights such a scenario.Case:A 75-year-old female with a history of cardiac arrest 30 years ago presented with shortness of breath and left leg swelling.
