EFFICIENT DELIVERY OF MULTI-SITE PACING

摘要

An implantable device and associated is disclosed. The device comprises a set of electrodes spatially separated from one another and all coupled to an implantable pulse generator. The device comprises a processor configured for forming a first pacing vector and a second pacing vector. The pulse generator is configured to deliver first pacing pulses to the first pacing vector and delivering second pacing pulses to the second pacing vector. The pulse generator generates a recharging current for recharging a first coupling capacitor over a first recharge time period and another recharging current for recharging a first coupling capacitor over a second recharging time period. An order of recharging the first and second coupling capacitors is dependent upon one of ventricular pacing mode, left ventricle to right ventricle delay (V-V) pace delay, multiple point LV delay and latest delivered pacing pulses to one of the first and second pacing vectors.
