Abstract: A method for managing bradycardia through vagus nerve stimulation is provided. An implantable neurostimulator configured to deliver electrical therapeutic stimulation in both afferent and efferent directions of a patient's cervical vagus nerve is provided. An operating mode is stored, which includes parametrically defining a maintenance dose of the electrical therapeutic stimulation tuned to restore cardiac autonomic balance through continuously-cycling, intermittent and periodic electrical pulses. The maintenance dose is delivered via a pulse generator through a pair of helical electrodes via an electrically coupled nerve stimulation therapy lead independent of cardiac cycle. The patient's physiology is monitored, and upon sensing a condition indicative of bradycardia, the delivery of the maintenance dose is suspended.

Abstract: Systems and methods are provided for delivering neurostimulation therapies to patients. A titration process is used to gradually increase the stimulation intensity to a desired therapeutic level. Between titration sessions one or more parameters, such as, for example, an acclimation interval, may be adjusted based on the patient's response to the stimulation. This personalized titration process can minimize the amount of time required to complete titration so as to begin delivery of the stimulation at therapeutically desirable levels.

Abstract: A system and method for providing cardiac pulmonary nerve stimulation (CPNS) with therapy titration, a goodness indicator, and therapy weaning. Therapy titration can include using physiological measurements of contractility, lusitropy, and chronotropy to determine therapy efficacy and adjust therapy delivery. For example, the electrode position and stimulation intensity can be adjusted based on the physiological measurements. Therapy titration can include closed-loop therapy delivery, in which therapy is automatically adjusted based on the measured physiological parameters. A goodness indicator can be used to monitor cardiovascular parameters such as contractility, preload, lusitropy, systolic function, and/or chronotropy. The goodness indicator can determine whether the change in these parameters from nerve stimulation is positive, and further indicate optimal stimulation. Therapy weaning can include gradually reducing stimulation while ensuring no significant reduction in therapeutic efficacy ensues.

Abstract: A method of neurostimulation titration includes titrating a neurostimulation signal from a first set of parameters toward a target set of parameters according to a titration aggressiveness profile having a titration hold point. The method further includes receiving a hold indicator indicating that the titration has reached the titration hold point. The method further includes initiating an intermediate hold of the titrating of the neurostimulation signal in response to receiving the hold indicator. The method further includes receiving an indication of a titration resumption that discontinues the intermediate hold.
