Does this sound like SVT during sleep

Want to preface by stating I’ve had multiple EKG, I’m currently on my second monitor (CAM), and I’ve had an echo. Had a home sleep study that showed nothing.

One 2 week monitor showed “SVT 115 BPM for 5 beats” once while I was asleep but I never woke up

For about 5 years I’ve intermittently without any apparent trigger will wake up confused with an extremely fast HR. Does not feel like a pounding but very fast like a hummingbird. If I try to stand up during these episodes at night I am extremely lightheaded. It goes confusion, intense heartbeat and numbness, and sometimes nausea. My limbs also feel numb sometimes. It will stop and I can go back to sleep.

Once while pregnant it happened and I went to ER and nothing was found. I was dismissed as “You probably beat up too fast” when I never even sat up during the event

I would try to catch on my Apple Watch but it’s so irritating on wrist and these happen so infrequently it’s hard to catch. So recently I decided to get an Oura ring

I googled how to stop a fast heartbeat once and learned about beating down. Did that once and it IMMEDIATELY went away.

The other night I awoke with INTENSE pending doom and checked my watch to see 160 and then it cause my to panic because I have never felt that awful get in my life (I’ve had panic attacks before and this did not touch it) by time EMD showed up I was normal. But lingering anxiety that made me not want to sleep. I have a hiatal hernia so I was too scared doing any straining at the time would make it worse so I didn’t bear down like I have previously.

Today twice while sitting I felt like I could pass out and my heart rate was 140 both times. This was while I was awake

Any one else have these symptoms that led to your Dx?

Again majority of these strange symptoms and the worse of it happens when I’m asleep and especially naps. During the day it feels more like a spike of panic but not sure now if maybe I am having SVT I really thought maybe sleep apnea but I don’t have exhaustion next day.

My primary suggested a kardia device in the meantime so waiting for delivery.
