Customizable titration for an implantable neurostimulator

A neurostimulation system comprises a control system configured to monitor a patient receiving neurostimulation therapy. The neurostimulation therapy has a stimulation cycle comprising a stimulation ON period, in which the patient is receiving neurostimulation, and a stimulation OFF period, in which the patient is not receiving neurostimulation. The control system is programmed to receive electrocardiogram (ECG) data from the patient receiving the neurostimulation therapy. The control system is further programmed to monitor a heart rate of the patient based on the ECG data over at least one stimulation cycle of the neurostimulation therapy. The control system is further programmed to generate an indication of signal stability to be displayed to a user based on the received ECG data.
