- 1-3mm upsloping ST depressions in V1-V6 with tall, symmetric T-waves is highly concerning for hyperacute proximal LAD STEMI.

- The T-waves in hyperkalemia are often simply narrow-based rather than tall. Because of this, the computer software often "double counts" the heart rate.
- In addition to the 1st line treatments of calcium, insulin-d10, bicarbonate and dialysis, effective treatment of hyperkalemia involves β2-agonists; 20mg albuterol nebulized over 10 minutes or terbutaline 0.5mg IV quickly drives potassium intracellularly.
- Proper treatment of most marine envenomations, catfish being the most common, is hot water soaks for 30-90 minutes with good wound care and a quinolone or augmentin for 5 days.
- CT abd/pelvis is only 92% sensitive for small bowel obstruction. Keep an open mind if you have strong clinical suspicion.
