Need medical detectives to help with my collapses!

I need help from all the smart people here. Any brainstorming and all ideas welcomed.

This morning I had to call the paramedics because I had another “collapsing episode.” Severe abdominal pain triggered low blood pressure and a very low heart rate. I was shaking violently and having trouble breathing, the latter seemed to be caused by the discomfort in my heart. I fought very hard not to lose consciousness. I was covered in cold sweat and my vision was blacking out. But the bradycardia and trouble breathing were the worst. It felt like my heart might just slow to a stop and I would be gone. It lasted for over half an hour — an eternity while panting with my HR in the low 40s when it should have been twice as fast.

The last time this happened, my doctor ordered a heart workup, which showed nothing, really (I’ve put the results below; I don’t really know how to interpret them). What I’m trying to figure out is if there is anything I should look into besides making sure my heart is okay. I’m on BP medication (to raise it), I don’t have POTS (as in, high heart rate)… I am so wiped out today and I can’t believe I just have to ignore these episodes, shrug and move on. What my heart did today was terrifying!

If anyone wants to help me play medical detective, here is the history of these episodes (no other health history included and there was a lot, obviously).

My episodes, as best as I can describe them, are vasovagal syncope. But they’re more complicated than that. It’s not a faint and then BP recovery once I’m supine. Abdominal pain/pressure/inflammation/cramping/spasm = BP and HR crash.

The first one I remember was in 2005 on the first day of my period. I used to have excruciating dysmenorrhea and one month it caused a collapse — on the bathroom floor, cold sweats, shakes, vision blacking out, very low BP. Went to the emergency room, got IV fluids.

This continued to happen once or twice a year until 2011 — and I can’t predict which months or why. It has happened when my period had nothing to do with it, but it was triggered by my bowels. I have had constipation my whole life, the last time I ever took a laxative was in 2008. The pressure/cramping caused the same low blood pressure, near-loss of consciousness result. My best friend held me up on the toilet while firemen filled my bathroom. As soon as my bowels moved and the pressure released, I recovered.

The only time I remember it not having anything to do with abdominal pain was one of the worst times. I spiked a fever and then collapsed on the front steps to my house and the medics couldn’t get a blood pressure reading at all. Went to the ER, got IV fluids.

I need to mention that all of this was pre-ME. An odd thing happened after ME destroyed my life in 2011– the dysmenorrhea stopped. I went 3 years without a collapsing episode, then had a random one in 2014 and not again until last year, once in February from random severe period cramps on the first day of menstruation (I think it might have been a burst ovarian cyst since it was so out of the norm) and once in July from a massive acute bowel spasm that was about a 9 on my pain scale.

(I should also mention that every time I went into full-blown anaphylaxis was at the start of my period. That started in 2001, four years before the collapses.)

The difference between these recent episodes (last year’s and today’s) and the pre-ME ones is it seems to be more about my heart and less about my BP. Both are low, but my BP isn’t scary-low (scary to EMTs, maybe, but not to me). I used to be able to not talk or move because I was so hypotensive, today I made it downstairs to open the door and had more awareness — was monitoring my HR and O2.

The past few days, I had a deep ache in the very bottom of my abdomen. I cannot have bowel movements and am completely enema-dependent with chronic pain and bloating, so I only noticed this pain because it was so low in my belly and deep-feeling. I kept looking for my period, thinking maybe it wasn’t my bowels, but was instead a heavy, achy uterus. When I went to sit up in bed, the pain skyrocketed, maybe my bowel spasmed like last year. I immediately started shaking and sweating, the vagal reaction happened right away. That’s my best guess — trapped gas in my very dysfunctional, SIBO-ridden bowel created pressure, pain and spasm that triggered a vasovagal response. The pain and bradycardia resolved at the same time and so did the shakes and panting, but I’ve been completely wiped out all day. I’m still in a lot of bowel pain now, 12 hours later, but it has moved up to its normal position in the upper abdominal quadrants.

So, any thoughts? With no period involvement, no actual bowel movement, and symptoms so severe that I called 911 (that is literally the SECOND since being sick — 9 years), I can’t believe I just have to ignore it and go on as usual, without answers. I mean, besides the obvious remove my bowel and remove my uterus, but I’m just not there yet.

Echocardiogram:
There is mild aortic insufficiency. Mild aortic regurgitation is present. There is an eccentric jet of aortic insufficiency directed towards the septum. There is trace mitral regurgitation. Trace tricuspid regurgitation present.

30-day heart monitor:
The vast majority of episodes show normal sinus rhythm without ectopy. Some episodes of dizziness show sinus tachycardia. One PVC and one blocked PAC were observed.
