Discussion See this post: STEMI with Life-Threatening Hypokalemia and Incessant Torsades de Pointes I could find very little literature on the treatment of severe life-threatening hypokalemia. If cardiac arrest from hypokalemia is imminent (i.e., When the ECG shows the effects of hypokalemia, it is particularly dangerous.

She had home health nurse visits, and a BMP was sent the next day (the day prior to admission, presumably after 120 mEq of KCl replacement -- if she was taking as directed). If cardiac arrest from hypokalemia is imminent (i.e., to greatly decrease risk (although in STEMI, the optimal level is about 4.0-4.5

Here is his ED ECG: There is obvious infero-posterior STEMI. What are you worried about in addition to his STEMI? Comments: STEMI with hypokalemia, especially with a long QT, puts the patient at very high risk of Torsades or Ventricular fibrillation (see many references, with abstracts, below). There is atrial fibrillation.
