APPARATUS AND METHOD FOR AN IMPLANTED CARDIAC PACEMAKER WITH MULTIUSE ELECTRODE WITH POTENTIAL RESTORATION

摘要

An apparatus for measuring an electrical potential in a human body by sampling the potential during a selected interval and storing the value of that potential at the end of the interval. The stored value of the potential will be restored as an initial value at the end of a second interval. The apparatus includes a timing circuit to identify appropriate intervals. Means are provided for sampling and storing the value of the electric potential at a given time and for restoring the measured potential to an electrode at a second selected time.
