The electrocardiogram (abbreviated ECG) is nothing but the graphical reproduction of the electrical activity of the heart, detected on the surface of the body by electrodes. It is used to analyze the good functioning of the patient's heart. At Centro Medico Polispecialistico Porta a Terra srl we perform classic cardiac ECG and dynamic 24h electrocardiograms. In this mode the patient is given electrodes connected to a portable device that records the cardiac electrical activity continuously within 24 hours and whose tracking is then detected and analyzed by the cardiologist.
