Figure 5: The original tracings of BP, respiration (Resp), and ECG before, after vagotomy and after diltiazem in vagotomized animals are presented on the left. Vertical dashed line indicates the point of capsaicin administration. Horizontal line (time scale) = 5 s for all. The mean ± SEM values (n = 3) of MAP, RF, and HR at immediate (Immed), intermediate (Inter), and delayed phases are presented in the bar diagrams. Before indicates before vagotomy; + VagX indicates after vagotomy; and + Dilt indicates diltiazem after vagotomy. *(P < 0.05, One-way ANOVA followed by Student-Newman-Keuls test)
