Patient 008 blood pressure and heart rate tracing during CSN Stimulation. A small delay can be seen between the application of stimulus and response. Note that different contacts were stimulated in different stimulation epochs which explains the heterogeneity of wave morphology. The stimulation epoch marked by the arrow caused BP to drop enough to trigger a protocol-mandated immediate withdrawal of stimulation.
