Causes of ECG artefacts mimicking arrhythmias
The Introduction to cardiac arrhythmias page has been updated with a short segment on common causes of ECG artefacts mimicking arrhythmias.
Updates
Delayed phase anaphylaxis
The Anaphylaxis page has been updated to better emphasise the rarity of delayed phase anaphylaxis in ED patients and to avoid routine long periods of observation for patients with anaphylaxis otherwise improved with therapy.van der Zwet, K. V. M., van Vossen-Treur, D., Venema, E., Guillen, S., & Moore-van Leest, E. J. (2022). Biphasic Allergic Reactions … Read more
Clot retrieval for basilar artery occlusion
The Stroke management page has been updated with additional information about the benefit of clot retrieval for basilar artery occlusion.Tao, C., Nogueira, R. G., Zhu, Y., Sun, J., Han, H., Yuan, G., Wen, C., Zhou, P., Chen, W., Zeng, G., Li, Y., Ma, Z., Yu, C., Su, J., Zhou, Z., Chen, Z., Liao, G., Sun, … Read more
PE and heart rate
Various pages have been updated to re-emphasise that heart rate is only > 100 bpm in about 40% of patients, so it is not a good screening variable. Increasing heart rate, however, is a good indicator of poorer prognosis.Yamashita, Y., Morimoto, T., Takase, T., et al., (2023). Impact of Heart Rate at Diagnosis on Clinical … Read more
Nitrates are not contra-indicated in RV infarction
The Management of ACS page has been updated to more clearly emphasise that nitrates are not contra-indicated in RV infarction, but some caution may be required due to potential hypotension.Wilkinson-Stokes, M., Betson, J., & Sawyer, S. (2022). Adverse events from nitrate administration during right ventricular myocardial infarction: a systematic review and meta-analysis. Emerg Med J. … Read more
Capitellum fractures
The Elbow injuries page has been updated with a short segment on capitellum fractures.
Balloon tamponade of oesophageal varices
The Upper GI haemorrhage page has been updated with new segment on balloon tamponade of oesophageal varices.

Emphysematous cystitis
Additional information about emphysematous cystitis has been added to the Urinary tract infection in adults page.
Pacemakers and MRI
The Magnetic resonance imaging page has been updated with additional information about pacemakers and MRI.
