A method and device for the pharmacological cardioversion of fibrillation or atrial flutter is disclosed. The device is implantable in the human body and provides equipment for drug infusion using an electrocatheter positioned in the right atrium, the right ventricle, or the coronary sinus. The electrocatheter is provided with sensors which monitor the electromechanical activity of the heart and which intervene to activate the infusion in the presence of fibrillation or flutter. The catheter may be provided with at least one balloon which can be inflated and deflated to create a chamber which permits perfusion of the drug directly into the vein of Marshall. |
