Hello, 35 yr old mother of 1 toddler. Happily married. Always had a murmur, palpitations since teens. Past 7 years, have had episodes of racing heart or "more complicated" palpitations. Seems worse around menses. I've had a mix of Sx's the past year- began w/ feeling sluggish. Followed w/ myriad of Sx's which overlap and come and go: Episodes of racing heart (170 bpm) at rest relieved with vagus nerve stimulus. Before an episode, would feel an adrenaline rush, afterward would have to empty bladder several times & have terrible chills. Unexplained weight loss, then weeks later loss of appetite, extreme exhaustion, insomnia, lowered bp but still normal, night sweats, numb feelings that moved all over body, differing palpitations, SOB, lungs would quickly inhale & exhale automatically but much faster than I can do intentionally, numb chin, mild lower abd muscle contract's similar to hypervent sx's, dizzy, excessive forgetfulness & confusion, full "watery" feeling in upper-mid abdomen, when lying flat (and taking shorter breaths) I believe the alveoli in my lower lobes collapse, when I take a deep breath I can feel wheezing as they open, dull or sharp CP, hard to get satisfying breath (as if breathing thin air), HA @ base of head, near syncope, fatty food causes pounding heart. Several heart monitors- neg, echo- neg, cxr- normal, brain ct normal, ekgs normal except right bundle branch block, blood work- slightly low K, slightly elevated WBC, normal tsh, neg for anemia, normal b vitamins and iron, elevated d-dimer, chest ct neg for PE. Began taking vitamin B12 & B6- gradually relieved most sx's within 2 months except exhaustion. EP study- Afib, but never had it before or after ep study. No meds except b vitamins. Emotionally, I've been through the ringer with this. Not ready to die, want more babies, have much more living to do. Positive outlook.
