Figure 2.
Effects of cardiac plexus blockade on stellate hemodynamic sympathetic response. On each graphic, LVP is represented at baseline and after stellate ganglia stimulation (RSGS and LSGS). After lidocaine injection (on the right), baseline incremental sympathetic changes on LVP induced by either RSGS and LSGS were abolished, which was accompanied by elimination of LV dP/dT sympathetic response. LVP= left ventricular pressure. LV dP/dT= rate of left ventricle pressure change. LSGS= left stellate ganglion stimulation. RSGS= right stellate ganglion stimulation. SG= stellate ganglion.
