The link to the ECG on ecgpedia is here (sorry the image doesn't seem to appear well on the blog)
As far as treatment goes:
Alternatives: bicarbonate, resonium
What else would you like to do: Call for help, move the patient to a higher dependency area, investigate and treat the AKI.
Would your initial treatment have been altered if in fact the ECG looked like this?
The T waves are a bit pointy but there is no QRS prolongation here......I'd be less worried and would want to re-check the potassium and would withhold the Calcium. An ABC approach with appropriate management of shock etc etc never goes amiss
In order to get some prescribing resources out there we intend to publish a series of prescribing problems on the website. The problems will appear at least weekly with the "answers" appearing a couple of days later. We'll use the standard exam stationery available on the LSE, but also available below in case you haven't got access to the LSE.
