A pacemaker is a small device that is implanted just below your collarbone through a small incision carried out under the effects of local anesthetic. A wire is lead to the heart and it’s lodged in the tissue of your heart. Electrical impulses will normalize the heart rythm.
An implantable cardioverter-defibrillator (ICD) is a small battery-powered device placed in your chest to monitor your heart rhythm and detect irregular heartbeats. An ICD can deliver electric shocks via one or more wires connected to your heart to fix an abnormal heart rhythm.
The electro anatomical mapping is a system that allows the specialist to reconstruct the heart cavities for their analysis. It also allows the physician to identify the places where the heart is malfunctioning and to correct them by heat (radiofrequency ablation) or freezing (cryoablation).
