An abnormal heartbeat (also called an arrhythmia or dysrhythmia) is any of a group of conditions in which the electrical activity of the heart is irregular.
The heartbeat may be too fast (over 100 beats per minute) or too slow (less than 60 beats per minute) and may be regular or irregular. A heartbeat that is too fast is called tachycardia, and a heartbeat that is too slow is called bradycardia. Although many arrhythmias are not life-threatening, some can cause cardiac arrest.
Much like class 1b antiarrhythmics, cocaine is well known to be a voltage-gated sodium ion channel blocker, which may cause potentially fatal arrhythmias such as ventricular tachycardias and QT interval elongation at higher doses.[1] Parasympatholytics such as atropine block the vagal effects of acetylcholine on the sinoatrial node, often resulting in sinus tachycardia, hence atropine is often used clinically for symptomatic bradycardia.[citation needed]
In the context of substance usage, many compounds alter one's heartrate. For example, stimulants tend to increase one's heart rate whilst depressants tend to decrease it. Combining the two can often result in dangerously irregular heartbeats.
