Supraventricular Tachycardia - What Increases Your Risk

Some lifestyle factors can raise your risk of having an episode of supraventricular tachycardia, such as overuse of nicotine or alcohol, or use of illegal drugs, such as stimulants like cocaine or methamphetamine.

Doctors also warn against using nonprescription diet pills or "pep" pills, because many contain ephedra, ephedrine, the herb ma huang, or other stimulants.
