ABSTRACT:
A transvalvular impedance measurement made between an atrium and a ventricle electrode of a standard implanted electro-catheter may be used to provide information indicative of the mechanical state of the heart. This information may be used, for example, to control the pacing rate of a rate responsive pacemaker, stimulation intensity self adjust or pacing mode switching. Other uses are also possible in defibrillators.
