Abstract
Electrocatheter for sequential cardiostimulation, comprising one or more atrial electrodes and one or more ventricular electrodes connectable to a dual chamber pacemaker via respective interface connectors, said electrocatheter being suitably shaped to allow the insertion thereof into the coronary sinus so as to position the atrial electrodes within the coronary sinus in correspondence of the left atrium of the heart, and the ventricular electrodes within the great cardiac vein where the anterior interventricular begins, in correspondence of the left ventricle, wherein the ventricular electrodes are located close to the distal end of the catheter to allow the ventricular stimulation and sensing, and wherein the atrial electrodes are suitably spaced from the ventricular ones and disposed upstream thereof to permit the atrial stimulation and sensing.
