Pharmacology – Drugs for Ventricular Arrhythmias – Lidocaine
Added on day of publication – Can it be used? Yes – there is some evidence – e.g. here – supporting its use, and in other countries including America it is one of the ‘first line options’ (Ray and Clemins, 2025). But should it be used in the UK? Here’s what the BNF says:
Intravenous lidocaine hydrochloride can be used for the treatment of ventricular tachycardia in haemodynamically stable patients, and ventricular fibrillation and pulseless ventricular tachycardia in cardiac arrest refractory to defibrillation, however it is no longer the anti-arrhythmic drug of first choice.

It’s always worth checking your local and country-specific guidelines before following any treatment algorithm.
