Increased heart rate
This is a common effect of stimulating substances especially stimulants as a direct result of dopaminergic or adrenergic modulation. It can also be a psychological effect, such as a natural adrenal response to shock or fear. As awareness is heightened, such responses often become more heightened, especially with astonishing or confusing hallucinations. Other mechanisms for increased heart rate exist as well, such as deliriants effect as an acetylcholine inhibitor, one of the main modulaters of heart rate in the peripheral nervous system.
