MAINTAINING HIGH PACE RATE CHARGE BALANCE

摘要

Disclosed are a charge balance apparatus and a method for balancing at least one pacing electrode electrically coupled to the charge balance circuit. The charge balance apparatus receives a pace waveform from a pulse generator and provides a balanced flow of charge to the at least one pacing electrode. A charge monitor circuit is electrically coupled to the at least one pacing electrode and measures a flow of charge through the at least one pacing electrode in a first direction. A logic circuit interrupts a flow of charge in a second direction when a measured flow of charge in the second direction is substantially equal to a measured flow of charge in the first direction.
