What can trigger an svt attack?

SVT is usually triggered by extra heartbeats (ectopic beats), which occur in all of us but may also be triggered by:

  • some medications, including asthma medications, herbal supplements and cold remedies
  • drinking large amounts of caffeine or alcohol
  • stress or emotional upset
  • a change in posture
  • smoking lots of cigarettes

What can trigger SVT? In some people, episodes of SVT can be triggered by exercise, stress, gastrointestinal symptoms (such as nausea, vomiting or constipation) or medications. But in most people, SVT appears to occur for no particular reason at all.

What is the best drug treatment for SVT? Typical medicines used to treat svt include beta blockers or calcium blockers. Some svts require more potent medications or an invasive procedure called ablation. The key is to capture and define the specific rhythm problem – that will dictate the treatment. Good luck.

Can SVT be cured? Svt can be controlled but not cured with medications. These have to be taken continuously in order to help prevent recurrences. A “cure” can be achieved with a technique called radiofrequency ablation or rfa.

Is SVT a heart attack? Not a heart attack. Supraventricular tachycardia (svt) is a rapid heart rate of 150 beats per minute, or higher. It is not a heart attack. A patient may feel he has a pounding heart (while not exercising).
