This week's web finds brings a host of ECG topics to demystifying papers to surviving the ED night shift.
As always, credit to the original posters.

• Ecg-of-week from JHC - Good ECG on John Larkin's site on a young female. Guess before looking at answer!
• Night-shift-for-junior-docs - EM tutorials gives a look at nocturnal med for the uninitiated
• Inhalational injuries - 5 minutes of vid is all that's needed for this topic
• Beware observational conclusions - Ryan shows how a paper on BP in stroke is not quite what it seems.
• Fraud in starch - Ever wondered how starch solutions made it into the resus world despite being nephrotoxic and relatively useless compared to other colloids? Read on.
• Hyperkalemia& ST segments - The excellent Dr Smith hands out gems with each ECG
• ABGs in trauma?  - A statistical deconstruction of this topic.

Here at Emergence Phenomena we're a bunch of minimalists. So the last link was something of an absolution. Looking for occult markers of bleeding is all well and good.
