Abstract
A technique utilizing an endolymphatically implanted lead having one or more electrodes that may be used for sensing cardiac activity and/or delivering cardiac electrical stimulation by an implantable cardiac device. An electrode disposed in the thoracic duct is in close proximity to the left ventricle and generates an electrogram especially suitable for ischemia detection and/or discriminating between ventricular tachycardias and supraventricular tachycardias.
