Electrophysiology studies and ablation

An electrophysiology study consists of an evaluation of the heart’s electrical activity and determinate the cause of the hearts’ abnormal rhythms, allowing to decide in relation to treatment and management. In children, it is usually performed under general anaesthesia. Small needle-punctures are made in the top of the legs that allow access to the veins, and through them to the heart.

Fine wires called catheters that allow to record electrical signals are then advanced through the veins into the heart to monitor the electricity in the different chambers and areas. Extra beats are delivered to check for the presence of abnormal electrical connections and to induce tachycardias, which can be reverted within a few seconds.

By this means, the doctors can diagnose the underlying problem and propose a treatment. In many cases, an abnormal electrical connection is identified within the heart and can be burned (or freezed) to permanently stop it from conducting electricity. This procedure is called ablation and has a rate of success of overall > 95%.

Doctor Gonzalez Corcia has a long expertise both in diagnosis of arrhythmias performing electrophysiology studies and treating the underlying mechanism by an ablation. When you meet Dr gonzalez Corcia, she will discuss with you/ your child the specificities of the procedure, the risks and benefits and the risks related to it.
