More Information
Summary:The composite electrode type intracardiac defibrillation catheter of the present invention includes a first electrode group including two or more first electrodes for detecting an electrophysiological electrical signal of a site or a cell group in a heart chamber, and a second electrode group including one or more second electrodes located between adjacent two of the first electrodes for causing an electric current by a high-voltage defibrillation electric shock for defibrillation to flow in a contact site in the heart chamber or in contact sites in the heart chamber and in a vein, and a conductive length of a surface of the second electrode in a longitudinal direction of the catheter shaft is longer than the conductive length of the first electrode.
