Improved methods for obtaining physiological parameters of a patient in accordance with various embodiments of the present invention can be used to monitor patient status and/or in conjunction with patient therapy. Physiological parameters can be monitored with an implantable device including a first lead and a second lead. Physiological parameters can be measured along at least three distinct vectors defined by the first lead and second lead, the first lead and an electrode located on the device body, and the second lead an the electrode. An output indicative of the physiological parameter can then be provided. Therapy, such as baroreflex therapy, can optionally be optimized based on the physiological measurements.
