LV performance to increasing Ca2+ concentrations in the perfusate was blunted in the hearts following T/HS lymph infusion. Changes in LVDP (A), +dP/dtmax (B), and −dP/dtmax (C) in response to Ca2+ in the perfusate. In control rat hearts, LVDP and the rates of rise (+dP/dtmax) and fall (−dP/dtmax) were increased with an acute increase in Ca2+ concentration. Responses to Ca2+ were depressed in hearts with T/HS lymph infusion. Data are expressed as means ± SE from 6 rats. *P < 0.05 vs. control and T/SS lymph groups.
