There were no dysrhythmias on cardiac monitor during observation. This discussion comes from this previous post: Hyperthermia and ST Elevation Discussion Brugada Type 1 ECG changes are associated with sudden cardiac death (SCD) and the occurrence of ventricular dysrhythmias. He was found to be influenza positive. Is there fever again?

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. The rhythm is atrial fibrillation. The QRS complex is within normal limits. These include.

Diffuse ST depression with ST elevation in aVR: Is this pattern specific for global ischemia due to left main coronary artery disease? Ischemia b. Opinions vary widely on the K level at which a patient must be admitted on a monitor because of the risk of ventricular dysrhythmias. ST depression: is it ischemia?

We see a regular tachycardia with a narrow QRS complex and no evidence of OMI or subendocardial ischemia. But adenosine only lasts for seconds, and if the dysrhythmia recurs, then the adenosine is gone. Prevent the initiation of the dysrhythmia -- this can be done with a beta blocker by prenenting PACS 2. Adenosine worked.

Now you have ECG and troponin evidence of ischemia, AND ventricular dysrhythmia, which means this is NOT a stable ACS. It they are static, then they are not due to ischemia. This is better evidence for ischemia than any other data point. Again, cath lab was not activated. What does this troponin level mean?

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? Severe hypokalemia in the setting of STEMI or dysrhythmias is life-threatening and needs very rapid treatment.

Doesn't this necessarily mean that he was having ischemia? He was admitted for monitoring and had no dysrhythmias. Although this is not a common phenomenon You will see it on occasion ( See the June 30, 2023 post the November 27, 2023 post and the July 24, 2013 post in Dr. Smith's ECG Blog ). She is very good.
