Sounds like you ar on the right track. As for MVP, that too is very common and mostly benign. I had a problem with Mitral Valve Leakage (regurgitation) for many years and it finally required surgery, but not until I reached the age of 67. That surgery was successful and relatively easy for me, I in fact enjoyed the time in the ICU as the nurses were great, caring people who were always positive and ready to help. I was in pretty good physical condition (especially for 67) at that time as I was still active including running for exercise. Yes, and not smoking for over 20 years.
Thank you for your kind words. I went to my primary physician the evening I posted this and in listening to my heart/reading my EKG he is pretty sure I have Mitral Valve Prolapse as well. I am to see a cardiologist this week for echo/stress test. I am hoping that all goes well.
I did quit smoking for about 6 moths last year but my stress ramped up again about halfway thru when my mother was diagnosed with stage 4 breast cancer after having a routine hip replacement surgery. She nearly died and it was so easy to go back to it for 'relief'. I am sure the cardio will tell me the same, just hoping the MVP has not degenerated to the point of surgery.
Life isn't fair, you've been hit with more than a share of health problems, my sympathy.
I believe you should see a cardiologist - assume the EKG was done by your primary care.. in any case, yes, discuss you new symptoms with your doctor.
I don't know much about RBB, but I believe it is mostly benign - don't know what the symptoms are outside of the EKG.
Given you family history and everything else we know about smoking, STOP. That alone will save $$$ just for the cost of the smokes... and many more $$$ on health issues. Yes, it can be difficult I was a smoker myself, but I quit over 25 years ago and think I would not be alive today if I had continued to smoke. I don't directly connect my atrial fibrillation problem with smoking, but overall my health is much better than had I continued to smoke.
The stress part, I have no ideas on how to address but know that can cause both heart problems and may be cured simply by removing the stress/anxiety.
If your heart rate is fast (I'd say over 80 at rest for your physical description) you should consider cutting out the caffeine - decaf may satisfy you "need" for some coffee/tea - it had worked for me for years, but I have gone back to drinking about 3 cups of regular coffee/tea a day and my HR seems unaffected. We react in different ways to stimulants.
I think you should also consider taking an aspirin a day, maybe a low dose. I say this for lots of reasons provided in your post. As the label say: if taken form more than a "few" days, consult your doctor. Millions of us take an aspirin a day, but some can't for stomach and other reasons.
Keep up the good work and focus love and kindness on those around you, especially family, this I am sure will help with the stress, yes, lowering stress for others helps lower stress for ourselves.
