Abstract
In recent years recording of monophasic action potentials (MAP) have become a powerful tool in experimental and clinical electrophysiology. Different recording techniques have been developed. The technique of suction electrodes [8,10,11] and the contact electrode technique developed by Franz [2,3,4] made the clinical application of catheters for MAP-recording possible. The contact electrode catheter technique is particularly clinically safe and reliable. Clinical use is currently limited to temporary measurements and chronically implantable MAP electrodes are not in use. With the development of novel iridium coated and fractally iridium coated electrodes, chronically implantable leads are available [6]. Fractally coated iridium electrodes have successfully been used as chronically implantable pacemaker leads for several years. Like the Ag-AgCl electrode, the fractally coated electrode is nonpolarizable. The fractally coated electrode has a large electroactive surface area, which results in a very low interface impedance. Fractal coating increase the electroactive surface [1].
