Bedside ED ultrasound showed exceedingly poor global LV function, and no B lines. Then I always look to see if the initial deflection of the QRS has a lot of voltage change per change in time (seen in tachycardias that are initiated from above the ventricle because the propagate through fast conducting purkinje fiber.

Bedside cardiac ultrasound showed moderately decreased LV function. See this post: How a pause can cause cardiac arrest 2. Even with tachycardia and a paced QRS duration of ~0.16 She was intubated. CT of the chest showed no pulmonary embolism but bibasilar infiltrates. The plan: 1. Place temporary pacemaker 3.

He had multiple cardiac arrests with ROSC regained each time. Cardiac Ultrasound may be a surprisingly easy way to help make the diagnosis Answer: pulmonary embolism. Now another, with ultrasound. Submitted by a Med Student, with Great Commentary on Bias! What is the Diagnosis? This is a quiz. Answer at bottom.

A bedside cardiac ultrasound was normal, with no effusion. This sinus tachycardia ( at ~130/minute ) — is consistent with the patient’s worsening clinical condition, with development of cardiogenic shock. He had the following EKG recorded: Low voltage, suggests effusion. There is minimal, probably normal STE in V2-V6.

This progressed to electrical storm , with incessant PolyMorphic Ventricular Tachycardia ( PMVT ) and recurrent episodes of Ventricular Fibrillation ( VFib ). Another approach is sympathetic chain (stellate ganglion) blockade if you have the skills to do it: it requires some expertise and ultrasound guidance.

Bedside ultrasound showed no effusion and moderately decreased LV function, with B-lines of pulmonary edema. See here for management of Polymorphic Ventricular Tachycardia , which includes Torsades. If cardiac arrest from hypokalemia is imminent (i.e., He was managed medically with Clopidogrel. He appeared to be in shock.

Is it ventricular tachycardia (VT) due to hyperK or is it a supraventricular rhythm with hyperK? On arrival, the patient was in shock, was intubated, and had an immediate cardiac ultrasound. What does a heart look like on ultrasound when the EKG looks like that? If cardiac arrest from hypokalemia is imminent (i.e.,
