A real time, heart rate monitor and a hemodynamic monitoring system are operably integrated with the programmer system for an implantable hypertension treatment device. A series of tests are automatically performed to set programmable parameters for the implantable hypertension treatment device without clinician intervention. In one embodiment, a predetermined level of a dose-response evaluation is initiated for each test in the series. Preferably, the programmer system monitors the heart rate to determine whether a hemodynamic measurement should be initiated at all for a given test, as well as whether the hemodynamic measurement should be initiated earlier or later than a predetermined settling period for assessing the sympathetic nervous response to the test dose. In one embodiment, this determination is based on heart rate stability/instability. Alternatively, other indicators of sympathetic/parasympathetic tone, such as heart rate variability, may be used to trigger/delay the timing of the hemodynamic measurement. |
