*For cardiac arrythmias: indicated if weakness, syncope, tachycardia runs with R on T complexes, ventricular tachycardia at rates >150bpm. Treated by correcting [[Essential Ion and Compound Balance and Homeostasis - Anatomy & Physiology#Acid / Base|acid-base]], [[Essential Ion and Compound Balance and Homeostasis - Anatomy & Physiology|electrolyte]] and [[Haemostasis - Pathology|haemostatic]] disturbances. The treatment is [[Local Anaesthetics#Lidocaine|lidocaine]] by bolus or continuous rate infusion or procainamide if they persist. | *For cardiac arrythmias: indicated if weakness, syncope, tachycardia runs with R on T complexes, ventricular tachycardia at rates >150bpm.
