ABSTRACT:
Cardiac lead implantation systems and methods including an electronics arrangement provided with a user interface and a coupler assembly. A coupler body is configured to detachably grasp a cardiac lead and couple with electrical contacts of the cardiac lead. A user interface includes an output indicative of sensed cardiac parameters, such as one or both of cardiac signal amplitude and lead electrode impedance, and may include an audio output device and/or a visual output device. Methods of lead implantation involve advancing a cardiac lead into proximity with a patient's heart, and contacting cardiac tissue with an electrode arrangement to locate a suitable implant location. Sensing of one or more cardiac parameters is accomplished and an audible representation of the sensed parameters is produced, the audible representation varying as the electrode arrangement is moved relative to the cardiac tissue.
