Abstract

Cardiac ultrasonically marked leads produced by mounting one or more piezoelectric marker transducers into the leads and connecting the transducers by electrical conductors to appropriate electronic circuits which, upon reception of the scanner ultrasonic signals by the marker transducers, generate appropriate electrical signals which localize unambiguously the marker transducers in an ultrasonic echographic image, thereby permitting guiding of pacing leads and detection of their malfunctions.
