How to Increase Heart Health

I’m only 32 and I have a pacemaker for sick sinus syndrome, and have been in torsades de points, svt tachycardia and junctional rhythms. It scares me, but we don’t even go to the hospital anymore when my heart rate gets up to 200. I’m afraid we’re gonna miss something serious going on with my heart, but I can’t be there every week. I’m lucky that my husband is a doctor so he monitors me and controls my medication but it’s scary. Adenosine doesn’t even work any longer to cardiovert me because I have the pacemaker.
