"Just watched Amal Mattu (and Andy Neill’s) great EKG review, this time on (spoiler alert) — hyperkalemia! (If you’re not watching these videos, you’re missing out on free, amazing education from I think the best EKG teacher in the world.)
You cannot — and should not — use an EKG to “rule out” hyperkalemia. I completely agree with Amal — if you see a bizarre looking EKG, you should think tox, potassium or calicum derangement (I like to throw LBBB in there too), but a normal EKG won’t rule out diddly squat in your patient."
