Active implantable medical device, in particular multisite pacemaker, defibrillator and/or cardioverter

摘要

Initialially the border between absolute and relative quiescent periods is moved from a total value covering depolarisation and amplifier recovery until a depolarisation detection signals an absolute quiescent period. The difference between this value and the programmed value becomes the relative quiescent period. In a second stage the stimulation amplitude is reduced in very small decrements (0.1V) until the highest cavity threshold is found
