The occurrence of supraventricular tachycardia (SVT) can be unpredictable. Sometimes, caffeine or exercise could trigger an SVT episode, but often it's not possible to predict when one will happen.
In general, SVT is not a life-threatening condition. Therefore, try not to allow a history of SVT to affect your quality of life.
However, if episodes of SVT happen frequently, you should talk with your health care provider about procedures, such as ablation or medical therapy, that might be able to cure the abnormal heart rhythm.
Prevention
One way to prevent SVT is to avoid substances that may cause the abnormal heart rhythm. These are commonly called triggers. Some common triggers include:
- Alcohol
- Cigarettes
- Caffeine
- Illegal drugs (cocaine, methamphetamine)
- Herbal supplements
You may be prescribed medications to prevent episodes of SVT. Remember to bring a list of all your medications to your appointments. In addition, don't use any medications or supplements without talking to your health care professional.
It's also important to keep up with regular health visits. If your symptoms get worse, or if you notice anything new, be sure to share those details with your health care team.
