 Heart rate response during progressive dynamic exercise in patients with coronary artery disease (n  =  15) given pyridostigmine (white squares) or placebo (black squares). The data points correspond to 20%, 40%, 60%, 80%, and 100% of peak oxygen uptake attained during each condition (connected by dotted lines). *p < 0.05 heart rate with pyridostigmine versus placebo at the same percentage of peak oxygen uptake; †p < 0.05 absolute V̇o₂ with pyridostigmine versus placebo at the same percentage of peak oxygen uptake. Data are mean (SE).
