Lehmann can't say how much of the effect was due to exercise and how much stemmed from other aspects of the stimulating environment. However, the relationship between the tempo of music and perception of effort during different metabolic demands is still unclear. Differentiate between a positive and a negative chronotropic agent. When exercise stops, there is an abrupt decrease in heart rate and cardiac output secondary to removal of the sympathetic drive and reactivation of vagal activity. “Knowing more about the effects of sildenafil on heart function will allow for safer evaluation of its use as a treatment for heart problems,” says Kass.
