Cardiac intracavity electrical conversion electrode catheter

The utility model relates to a cardiac intracavity electrical conversion electrode catheter. The cardiac intracavity electrical conversion electrode catheter comprises an electrode part and a catheter body, wherein one end of the catheter body is connected with the electrode part, the electrode part is divided into two electrode catheters, and an electrode is arranged on each electrode catheter. The cardiac intracavity electrical conversion electrode catheter has the advantages that the single catheter is economic in cost and has good maneuverability; the electrode catheter is put in a cardiac cavity, is attached to the crista terminalis of a right atrium and the free wall of a left atrium, and is simple to operate; the electrode catheter covers the atriums of both sides, can be used for electrophysiological examination and diagnosis arrhythmia mechanisms and can be used for temporary cardiac pacing; and an electric field is generated between the two electrodes to cover the atriums of both sides, the covering range is maximum, furthermore, the energy which is required by cardioversion is reduced, and a cardioversion effect is stable.
