Arrhythmia Ischemia Ultrasound 
Dr. Smith's ECG Blog
JANUARY 2, 2025
Bedside cardiac ultrasound showed moderately decreased LV function. It should be kept in mind that on occasions, beta-one agonist can result in increased ventricular ectopy e.g., in severe myocardial ischemia (by increasing myocardial demand), or sometimes with congenital long-QT syndrome. She was intubated.

Smith comment: This patient did not have a bedside ultrasound. Had one been done, it would have shown a feature that is apparent on this ultrasound (however, this patient's LV function would not be as good as in this clip): This is recorded with the LV on the right. What should be done? Should the cath lab be activated?

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?

His response: “subendocardial ischemia. Smith : It should be noted that, in subendocardial ischemia, in contrast to OMI, absence of wall motion abnormality is common. With the history of Afib, CTA abdomen was ordered to r/o mesenteric ischemia vs ischemic colitis vs small bowel obstruction. Anything more on history?

Her bedside cardiac ultrasound was normal We decided to cardiovert her since the time of onset was very recent. The Role of Sinus Arrhythmia: I found it interesting to compare the long lead II rhythm strips in the 3 serial tracings from today’s case ( Figure-1 ). But when you see this, you should suspect that the AV node is not well.

Here was his prehospital ECG, which I viewed immediately while the resident performed cardiac ultrasound: What do you think? Here is the cardiac ultrasound which the resident performed as I viewed the ECG: This shows a huge pericardial effusion. Therefore, we performed ultrasound-guided pericardiocentesis. Is is sinus?

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.
