This is a non invasive procedure used to correct an abnormal heart rhythm.

It is performed in the Cardiac Catheterisation Laboratory (Cath Lab) by a Cardiologist and cardiac team specialising in Electrophysiology. It only takes a few minutes, but the patient remains under surveillance and monitoring afterwards prior to discharge. Preparation and recovery may prolong the stay to 4 to 6 hours. An IV (intravenous line) is inserted into the arm or hand and a sedative or general anaesthetic administered which allows the patient to sleep throughout.

The procedure

ECG patches and self adhesive pads will be placed on the patient’s chest. Part of the chest may be clipped of hair before hand. The doctor will use a cardioversion machine to deliver electrical energy safely through the pads. The abnormal rhythm is interrupted and a normal heart rhythm restored.
