ABSTRACT:
A method for positioning an electrode catheter system having safety means at its distal section within a heart chamber comprises percutaneously introducing the distal end of a catheter through an artery or vein to the heart chamber. Once the catheter tip is at the desired location, the connector of the handle at the proximal end is connected to an EKG monitor. And the electrical signal from the electrodes on the distal section can be transmitted to the exterior EKG monitor for cardiac mapping. Alternately, the radio frequency current can be supplied to one or more of the electrodes on the distal section once an intimate contact with a tissue is achieved using the catheter of this invention.
