Decreased heart rate
Decreased heart rate or bradycardia can be described as a heart rate that is lower than the normal heart rate at rest. The average healthy human heart normally beats 60 to 100 times a minute when a person is at rest. When the heart rate fluctuates to lower levels under 60 BPM, it is described as bradycardia or an abnormally low heart rate.
Decreased heart rate is most commonly induced under the influence of heavy dosages of depressant compounds, such as GABAergics, and opioids. However, it can also occur under the influence of cannabinoids, dissociatives, and stimulants.
