Abstract
An automatic capture restoration and threshold-seeking method and apparatus for use with a cardiac pacemaker derives control signals for restoring cardiac capture from a cardiac pressure sensor. The pressure sensor also provides input control signals for a threshold-seeking apparatus. Both pulse width and amplitude thresholds can be changed contemporaneously during both capture restoration and threshold seeking.
