'''Abnormal heartbeat''' (also called an '''arrhythmia''' or '''dysrhythmia''') is defined as a problem with the rate or rhythm of a heartbeat.<ref>National Heart, Lung and Blood Institute. (2019). Arrhythmia. https://www.nhlbi.nih.gov/health-topics/arrhythmia</ref> 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 [[dosage#common|moderate]] [[dosage|dosages]] of [[stimulant]] and [[depressant]] compounds, such as [[cocaine]],<ref>O’Leary, Michael E, and Jules C Hancox. “Role of Voltage-Gated Sodium, Potassium and Calcium Channels in the Development of Cocaine-Associated Cardiac Arrhythmias.British Journal of Clinical Pharmacology 69.5 (2010): 427–442.

Combining the two can often result in dangerously irregular heartbeats.
