Prevention
You can reduce your risk of having
episodes of
supraventricular tachycardia by avoiding certain
stimulants or stressors, such as caffeine, nicotine, some medicines (for
example, decongestants), illegal drugs (stimulants, like methamphetamines and
cocaine), excess alcohol, lack of sleep, and overeating.
If fast
heart rates continue, long-term medicines such as beta-blockers may be used to
help prevent a recurrence of the fast heart rate.
