Hello. I'm new to the group, so glad to have found this support group. I recently had my first "ER" PSVT experience 2 weeks ago. Prior to that, I'd never heard of PSVT. however I do have genetic heart disease in my family (great grandfather, grandfather died of heart attack, dad has had stints as well as my uncle). I've always had heart flutters and a couple of times I've had resting heart rate of 100-120 (my apple watch has shot me warnings) however no other symptoms associated.
I'm fairly athletic - I'm a runner (never a marathon - only for 30 min cardio) - I LOVE spin, and I also indulge in crossfit a couple times a week. About a month ago I decided to try a "workout enhancement" called "Thrive". It's basically a 3 step system - you take a capsule when you first wake up, drink a shake 20-40 mins later, and then put this patch on. There is coffee bean extract and some other stuff in the patch. It really did enhance my workout, but the 3rd week I was on it I was taking a competitive spin class and pushed myself pretty hard - at the end of the workout my heart beat got "stuck" at 180. I got off the bike and went into the lobby - receptionist gave me a cold rag that I put on my face - it went away instantly. It freaked me out so I stopped the work out supplements and had only been on it a few weeks. 5 days later (2 Wednesday's ago) I was getting dressed for work and my heart rate shot up. I got really dizzy and panicked, went down stairs and put ice on my neck and face. It didn't help - so I called 911. When paramedics came they captured my heart rate at about 135-140 and took me into the ER. ER doc said everything was normal - gave me a bag of IV fluid and sent me home. I actually thought maybe I was dehydrated. Went home and within 15 minutes it came back, so went back to ER - my heart rate was stable by the time I got there so he gave me some proponalol and put a heart monitor on me. I took 2 doses of proponalol and it made me SO TIRED - I slept on and off for 2days. The monitor didn't pick anything up either.
Went to cardiologist 2 days later - he suspects PVST. I had vacation with my family scheduled a few days following my appt with him, so he told me to go on vacation and take a proponalol 1 hour before my flight (5.5 hour flight over ocean). I took half a pill and I feel like it made me much worse - it made me paranoid and just very strange for the first few hours until it finally settled and then I felt pretty relaxed. I'm still on vacation - got sun burned yesterday, felt dehydrated and faint - it triggered an attack. My resting heart rate got up to 145-150, so went into ER and they gave me metoprolol - did all the checks, ECG and blood work was normal. The ER DR here told me not to think so much about heart attack (honestly, it's really hard not to - it's scary). He gave me a script of metoprolol but told me to take it only as needed - not everyday.
My question is - how do Dr's really know it's PSVT or SVT? It's so similar to cardiac arrest and heart attack. I get an ECHO done next Tuesday after I'm home from vacation, and will also wear a monitor for a couple weeks to try and catch the episodes. I have no idea if we will get enough data from the monitor, and what the ECHO will show - was anyone else scared like me on the diagnosis being incorrect? I guess I've survived them so far, but my concern is that this may just be a sample to something more serious.
Thoughts? Thanks for any feedback/responses. It's difficult to come to terms with this bc it seemed to have happened overnight.
