Abnormal heartbeat

Abnormal heartbeat (also called an arrhythmia or dysrhythmia) is defined as a problem with the rate or rhythm of a heartbeat.[1] A heartbeat that is too fast (greater than 100 beats per minute) is called tachycardia and a heartbeat that is too slow (less than 60 beats per minute) is called bradycardia. Arrhythmias are caused by changes to heart tissue. Hearts beat due to cascading electrical signals and these can be influenced by stress hormones, electrolytes, and medicinal substances.

An abnormal heartbeat is most commonly induced under the influence of moderate dosages of stimulant and depressant compounds, such as cocaine,[2] methamphetamine, and GABAergics. While stimulants tend to increase a person's heart rate, depressants tend to decrease it. Combining the two can often result in dangerously irregular heartbeats.
