Physiological parameters of a patient can be used to monitor patient status and/or in conjunction with patient therapy. Physiological cycles may be monitored by implanting a monitoring system into the patient, the system including an implantable pulse generator operably connected to a lead implanted on a carotid sinus of the patient, measuring at least one signal indicative of a physiological parameter of the patient along at least two vectors selected from: a first vector defined between a first electrode of the lead and a second electrode of the lead, a second vector defined between the first electrode of the lead and an electrode integrated into an implantable pulse generator, and a third vector defined between the second electrode of the lead and the electrode integrated into the implantable pulse generator, and providing an output indicative of the at least one signal indicative of the physiological parameter.
