    • Methods and devices for configuring the use of a motion sensor in an implantable cardiac device. The electrical signals of the patient's heart are observed and may be correlated to the physical motion of the heart as detected by the motion sensor of the implantable cardiac device in order to facilitate temporal configuration of motion sensor data collection that avoids detecting cardiac motion in favor of overall motion of the patient. The implantable device comprises trigger means for determining that a predefined event has occurred in the heart of the patient using a signal from the electrodes and sampling means for sampling an output of the motion sensor in response to the trigger means. In another aspect, the implantable device comprises sampling means for sampling a signal from a motion sensor in the ID, baseline calculation means for analyzing the sampled signal over time to generate a baseline output of the motion sensor, present state means for determining a present state indicator from the sampled signal, comparing means to compare the present state indicator to the baseline to yield a difference, activity characterizing means to analyze the difference to determine the patient's activity level.

    • 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.
