This suggests further severe ischemia. The problem is difficult to study because angiographic visualization of arteries is not perfect, and not all angiograms employ intravascular ultrasound (IVUS) to assess for unseen plaque or for plaque whose rupture and ulceration cannot be seen on angiogram. And yet the arteries remain open.

A bedside cardiac ultrasound was performed with a parasternal long axis view demonstrated below: There is a large pericardial effusion with collapse of the right ventricle during systole. Alternation in ST segment appearance ( or in the amount of ST elevation or depression ) — is often linked to ischemia. She has already had syncope.

Her bedside cardiac ultrasound was normal We decided to cardiovert her since the time of onset was very recent. 25, 2022 ). But when you see this, you should suspect that the AV node is not well. I signed her out to one of my partners. He decided to give ibutilide 1 mg over 10 minutes.

He arrived in the ED and had an immediate bedside cardiac ultrasound while this ECG was being recorded. The bedside ultrasound (video not available) reportedly showed only a slightly reduced LV function. The patient was given 6mg, then 12 mg, of adenosine, without a change in the rhythm. Here is the ECG: What do you think?

In terms of ischemia, there is both a signal of subendocardial ischemia (STD max in V5-V6 with reciprocal STE in aVR) AND a signal of transmural infarction of the inferior wall with Q wave and STE in lead III with reciprocal STD in I and aVL. Now another, with ultrasound. The rhythm is atrial fibrillation. What is the Diagnosis?

I do not think this ECG is by itself diagnostic of OMI (full thickness, subepicardial ischemia ), b ut comparison to a previous might reveal this ECG as diagnostic of OMI.
