@eileenb1022 Hi and Welcome to connect. I am a former person that had VT just not the SVT you possibly have. So I can at least talk about what kept me going wharn I was diagnosed in 2008. My best advice now is to find the correct type of Cardiologist. You need a doctor that Handel's the electrical part of the Heart or what called an EP Cardiologist. You husband may have one that similar if he is seeing one for his afib but even among EP doctors the specialize between afib and VT. If these terms are new EP stands for Eltro Physiologist . Being it sounds like your having issues in NH I would plan a trip down to the Boston area or at least a larger city . I'm from Mass/RI area myself and I do know I see folks on here that really take up Mass General as a great hospital. I developed my issues here in Arizona where I live now. But your right that VT is nothing to wait to long to get addressed. It can be life threatening I know it was for me. I don't want to alarm you but I would not wait to long before seeing a specialist. Now once I was diagnosed it was recommended I get a pacemaker and it allowed me to continue working for many years. With proper treatment you won't have a problem still managing your life for many years. I was about your age when I was first diagnosed and didn't need more intervention until recently I'm now 62 myself and have a great n life. My heart ended up getting worse and 4 years ago I got a heart transplant but honestly for about 10 years I had a pacemaker with meds and was able to I do a very physical job in the communications industry climbing towers and working in remote mountain tops. So first step is a good EP Cardiologist I would recommend.
As a side note stress does make it worse so try to calm down as much as possible. There are also some great techniques to help during an episode. Similar to what they recommend to strengthen your pelvic floor muscles also helps your heart achieve a normal rhythm and also intense coughing will also help. But bearing down on the pelvic muscles does help I've used it myself. Please keep in touch and let me know if you have more questions and or let me know when you get to the doctor's.
Blessings
