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?

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?

Bedside ultrasound showed no effusion and moderately decreased LV function, with B-lines of pulmonary edema. If there is polymorphic VT with a long QT on the baseline ECG, then generally we call that Torsades, but Non-Torsades Polymorphic VT can result from ischemia alone. Could the dysrhythmias have been prevented?

Check : [vitals, SOB, Chest Pain, Ultrasound] If the patient has Abdominal Pain, Chest Pain, Dyspnea or Hypoxemia, Headache, Hypotension , then these should be considered the primary chief complaint (not syncope). Evidence of acute ischemia (may be subtle) vii. Aortic Dissection, Valvular (especially Aortic Stenosis), Tamponade.

There is no evidence of infarction or ischemia. A bedside POC cardiac ultrasound was done: Findings: Decreased left ventricular systolic function. There is a large peaked P-wave in lead II (right atrial enlargement) There is left axis deviation consistent with left anterior fascicular block. There are nonspecific ST-T abnormalities.
