Abstract: Devices, systems, and techniques are described for transitioning between different groups of electrical stimulation programs. For example, a system may control delivery of second electrical stimulation defined by one or more second programs of a second group of stimulation programs on a time-interleaved basis with first electrical stimulation defined by one or more first programs of the first group of stimulation programs. The system may change a first ratio of the one or more first programs used to define the first electrical stimulation to the one or more second programs used to define the second electrical stimulation delivered within a first period of time to a second ratio of the one or more first programs used to define the first electrical stimulation to the one or more second programs used to define the second electrical stimulation delivered within a second period of time.

Abstract: Devices and methods provide for the sensing of physiological signals by providing a stimulation waveform that includes a stimulation pulse followed by an active recharge pulse to clear the charge in capacitors within the stimulation path. The active recharge pulse is followed by a period of passive recharge and then a period of no recharge. Non-neurological sources of artifacts within the sensed physiological signal may be handled by providing a brief period of passive recharge followed by a lengthy period of no recharge, which is made possible by the use of the active recharge pulse prior to the passive recharge. The period of no recharge removes any low impedance path to ground from the stimulation electrodes, which allows an amplifier of the sensing circuit to provide common mode rejection of non-neurological signals, such as cardiac signals, present at the sensing electrodes.
