Cardiac arrhythmia ECGs upgrades
About 30 of the ECGs in the Cardiac Arrthymias part of the Resuscitation section have been upgraded to higher resolution images to make it easier to see all of the relevant features. Link
CHB with ventricular standstill
A new ECG has been added to the Resuscitation section demonstrating CHB with ventricular standstill. Link
VT ECG
A new ECG demonstrating a less obvious form of VT has been added to the Resuscitation section. Link
Mobitz type II
An additional Mobitz type II ECG has been added. Link
1st degree heart block
An additional ECG demonstrating first degree heart block has been added. Link
Multiple sinus pauses
An ECG demonstrating multiple sinus pauses / arrest has been added. Link
Atrial flutter fest
3 new ECGs demonstrating unique features of atrial flutter that can make the diagnosis difficult have been added. Link 1 Link 2 Link 3
AIVR ECG
Another ECG demonstrating AIVR has been added. Link
SVT and accessory pathway ECG
Another ECG demonstrating SVT through an accessory pathway has been added. Link
Accessory pathway ECG
An additional ECG demonstrating an accessory pathway with ventricular pre-excitation has been added. Link
Salt ingestion
Salt ingestion is an uncommon cause of hypernatraemia, but 0.75 – 3g/kg can be potentially fatal. One tablespoon of salt weighs about 15 g. Link
LP RBC counts in suspected SAH
How the LP RBC counts may influence the diagnosis of SAH has been added following a recent study in Academic Emergency Medicine. Link
Beta blockers vs calcium channel antagonists for AFib
Despite diltiazem having a theorretical advantage of causing less hypotension, a retrospective study in Academic Emergency Medicine did not show any signfiicant differences in outcomes in patients with AFib treated with dilatiazem, verpapamil or metoprolol. Link
Suxamethonium vs rocuronium – which is better?
Great to see that there has been some response to the poll of the preferred muscle relaxant used for intubation in the ED. At this point it appears to be a 2 horse race between suxamethonium and rocuronium. Get your vote in soon as the poll will be closing in the next few days. Feel free … Read more

In particular, the bullets on some lists seem to want to have different sizes, and some hyperlinks want to underline themselves – but … Read more
Extracorporeal elimination of toxic compounds
The Extracorporeal methods of drug elimination page in the Toxicology section has had a major update following the recent symposium on the subject in Copenhagen.
Seizure assessment and management
The pages relating to seizures in the Neurological Disorders section have been revised and restructured to aid in navigation.
Salicylate toxicity
The Salicylates page in the Toxicology section has been updated.
Metformin toxicity
