[|Human|] Hi, I have been having SVTs since falling pregnant with my first child in late 2004.  I cam off beta blockers in may last year and have had a few SVTs since then , but they have not required hospital treatment.  I have read that they can prove to befatal, is this true as my consultant said they were not fatal.  Can it be controlled by diet at all?
[|AI|]  Hello Welcome to Chat Doctor. Most Sets are usually not life-threatening. When there are accompanying complications like low BP, previous heart disease then they may cause issues. But usually Sets are not troublesome. There are no diet modifications that can prevent Sets. They happen due to some improper circuit within the hearts' conduction system. Medications like beta blockers do not cure SVT, to inhibit the trigger which leads to SVT. The keep the heart rate low so that Sets sent occur. Since you are still getting them, I recommend you should be on a small dose of Clapton (calcium channel blocker) daily for your SVT. They have very less side effects and tolerate well by all patients. Another approach that is used for patients with low risk Sets is to take a Clapton 120 mg SOS during the episodes. Since I have not examined you and seen your records, I would recommend the daily dosage of Clapton approach. Wishing you good health Regards
