Non-randomized trials show better outcomes (neurologic survival) using this device; see this article in Resuscitation: Head and Thorax Elevation during cardiopulmonary resuscitation using circulatory adjuncts is associated with improved survival. The patient had ROSC and maintained it.

A fascinating electrophysiology case. What is this wide complex tachycardia, and how best to manage it?

Dr. Smith's ECG Blog

She presented to the emergency department after a couple of days of chest discomfort. The ECG was interpreted as showing atrial flutter with 2:1 conduction. The heart rate could be compatible with that of a 2:1 conducted atrial flutter. Also, lead I could give the initial impression of showing flutter waves.

Ischemic ST depression maximal in V1-V4 (vs. V5-V6), even if less than 0.1 millivolt, is specific for Occlusion Myocardial Infarction (vs. subendocardial non-occlusive ischemia)

A 50-something man with history only of alcohol abuse and hypertension (not on meds) presented with sudden left chest pain, sharp, radiating down left arm, cramping, that waxes and wanes but never goes completely away. A chest X-ray was obtained: This was read by radiology as "Bilateral lower lobe interstitial opacities.

Atrial fibrillation? Multifocal Atrial Tachycardia? Don't look at computer read until AFTER you interpret!

Dr. Smith's ECG Blog

This 60-something with h/o COPD and HFrEF (EF 25%) presented with SOB and chest pain. A deep neural network for 12-lead electrocardiogram interpretation outperforms a conventional algorithm, and its physician over-read, in the diagnosis of atrial fibrillation. The patient in this case presented with dyspnea and chest pain.

New Onset Heart Failure and Frequent Prolonged SVT. What is it? Management?

Dr. Smith's ECG Blog

This middle-aged man with no cardiac history but with significant history of methamphetamin and alcohol use presented with chest pain and SOB, worsening over days, with orthopnea. There is atrial activity before every QRS, but that activity has negative polarity, so it is not sinus rhythm. The other atrial flutter types are: 1.

What is this rhythm? And why rhythm problems are easier for the Emergency Physician than acute coronary occlusion (OMI).

Dr. Smith's ECG Blog

Possible but, again, the QRS morphology is atypical 3) Atrial Flutter with 2:1 conduction and "aberrancy". I do not see flutter wave baseline, and again the QRS morphology is not typical for a supraventricular rhythm. With OMI, all you know is that your patient has some nonspecific chest pain, SOB, shoulder pain etc.
