Also known as: ventricular tachycardia, rapid heartbeat
Tachycardia is the medical term for a rapid heartbeat. This can impact the upper chambers of the heart, the lower chambers of the heart or both. It varies in severity and can lead to complications in many instances if left untreated.
The condition occurs due to an electrical problem with the heart. This can occur because of certain medical conditions or the use of some medications. Using caffeine, nicotine, alcohol or other drugs can increase the risk.
