<p>A method and apparatus for locating a catheter (1) adjacent to a pacemaker node (PN) of the heart. The catheter tip location just before SA heart pacemaker node is desired because is most often the safest and optimal location. The catheter is placed by a physician within a patient's body circulatory vessel. From the distal tip (10) of the catheter the endogenous electrical activity from the SA pacemaker node of the heart is monitored. As the catheter is advanced within the circulatory vessel, the electronic catheter monitoring system (50) monitors the natural pacemaker node potentials, which increase as the node is approached and decrease as the node is passed. The information provided by the electronic catheter monitoring system is used by the physician to guide catheter placement and confirm its location at the desired location outside the heart before the SA node.</p> |
