Multipolar Transesophageal Leads Sensitivity and Selectivity

Standard esophageal pacing leads produce a symmetrical electric field and stimulate not only the heart but the surrounding tissue ass well. We introduced a new type of esophageal lead and called it � a selective esophageal pacing lead� . This lead is suitable for recording of esophageal ECG and pacing of either cardiac chamber. In this paper, electrical parameters of the selective esophageal lead are defined and used for comparing of leads with different angular electrodes. These parameters describe the sensitivity and the selectivity of the lead. The selective lead consists of the mechanical part which is implanted into the esophagus and of electronic circuits that enable its proper function, i.e. producing of an electric field directed into the wanted direction, towards the heart.
