supraventricular tachycardia (SVT) is a fast heart rate caused by abnormal electrical impulses above the ventricles. It's an important condition for paramedics to recognise, as it often requires a pre-alert and blue light transfer to the hospital to slow the heart rate down. We cover how to identify SVT on an ECG, the common symptoms it can cause, and how it can sometimes present with a broad QRS complex, making it difficult to distinguish from ventricular tachycardia.#SVT #SupraventricularTachy
