Hi Rob and Welcome to the Cardiac Forum of HealingWell!!
I found a site that may help explain better than I...re SVT's.
Hope this helps to give you some good info! :)
A lot of people have been diagnosed with MVP and live their
whole lives with absolutely no problems - it sounds like you've
pretty much had little problems with this?!
It's when the valve becomes stenosed or you have severe regurgitation
is when the problems begin, but even then...you can go for years with
no problems. I do not have MVP, but was diagnosed with Mitral Valve
Stenosis/Calcification and Regurgitation - I've had no problems and mine
has been considered to be between mild and moderate. I've really
never noticed any trouble as yet, and hopefully I never will!!
Let me know if the article helps, Rob?! My best wishes to you!
