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 (such as stimulants like cocaine and
methamphetamines), 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.
