ABSTRACT:
A capture verification system for a cardiac pacemaker comprising an implantable pulse generator (IPG) and one or more pacing leads having a proximal end coupled to the IPG and a distal end in contact with a patient's heart. The capture verification system employs a pressure wave sensor mounted in the IPG in relation to the proximal end of the pacing lead for sensing pressure waves transmitted from the distal end of the pacing lead to the proximal end thereof. The pressure waves include characteristic sounds of heart contraction and/or distal end lead motion caused by the contraction motion of the patient's heart that are transmitted along the lead body to the active sensor. A further isolated, reference sensor is also incorporated into the IPG in a similar fashion. Signal processors are coupled to the pressure wave and reference sensors for nulling out common mode noise.
