I am 39 year old, female, diagnosed with SVT in August 1998.  The physician gave me Digoxin, but said I wouldn't have to take it unless the SVT became a problem.  I have not took any to date.  Recently I had a short episode that I was able to stop.  Since that time I've had several episodes of SVT lasting only a few seconds.  Do you think the Dig would be helpful.  My resting heart rate is usually between 60-72 and I know Dig will slow the heart rate down, but since my restint HR is fairly low, do you think the Dig would be harmful.  Also, is there anything to help the bothersome premature beats.  The physician said I had Supraventricular Extrasystole also, and it's about at aggrevating at the SVT.
Thanks



  
Dear Kim, thank you for your question.  Premature beats are usually precipitated by alcohol, tobacco, caffeine, and stress so anything that you can do to avoid those precipitants would help.  The digoxin was recommended to slow down the SVT when it develops and it probably won't affect your native, resting heart rate.  SVT is usually caused by an extra electrical conduction pathway between the atria and the ventricles and can often be cured with a procedure called radiofrequency ablation (RFA).   During a RFA procedure, catheters are inserted through the veins in the groin and are used to map extra electrical pathways.  Through these same catheters, radio wave energy can be applied to the extra electrical pathways to eliminate them and cure the SVT.  Alternatively, medications like digoxin or beta-blockers can be used to slow down the rate of SVT if it develops. SVT is rarely dangerous but certainly can be a nuisance.  Thus, you may want to speak to a cardiologist regarding a RFA procedure.  
I hope this information is useful. Information provided in the heart forum is for general purposes only.  Only your physician can provided specific diagnoses and therapies.  Feel free to write back with further questions. Good luck!
