Abstract
A cardiac sensing lead which is placed and used on the epicardial surface of the heart. The lead consists of a screw-in electrode which acts as the cathode and a mesh of platinum/iridium that acts as the anode. The electrodes' effective distances from each other are no longer than lcm. The screw-in electrode also acts as the anchor in the tissue and is implanted with a lead applicator. The cardiac sensing lead senses cardiac signals for the application for diagnostic purposes such as for an internal defibrillator or any other external or internal medical devices.
