Supraventricular tachycardia (SVT) — Take-home summary
The essentials to keep, discuss, and use between visits.
Understand your condition
SVT is a fast rhythm involving electrical activity above the ventricles. Episodes often start and stop suddenly. Several types exist, and many common forms can be cured with ablation.
Everyday care
- Know your personal episode plan. Use a vagal maneuver only as your clinician has taught you; do not massage your neck.
- Take an episode medicine only if prescribed for that purpose.
- Record episode timing, duration, and symptoms when safe.
When to contact your care team
Contact your care team if episodes are new, more frequent, longer, or interfere with daily life. Follow your personal plan when an episode will not stop.
When to call 911
Call 911 if racing occurs with chest pressure, severe trouble breathing, fainting, or severe weakness or dizziness. Do not drive yourself.
Questions for your next visit
- What type of SVT do I have?
- What should I do during an episode?
- Is ablation an option?
