Experiencing Chest Zaps at Night, Need Advice

I had all kinds of tests done and everything was negative. So they ruled as that.

Yeah songs like panic disorder. I’ve experienced this exactly

I've been having these every night for the past 5 months. I'm being referred to a neurologist. I believe they're called hypnic jerks

I have been experiencing similar symptoms for a while.I think I have something called gastrocardiac syndrome though I haven't been able to get a formal diagnosis yet. I experience palpitations and breathlessness, overwhelming panic, confusion etc when I lie down and try to sleep, or sometimes when I suddenly wake up

I don't feel a zap exactly, but I get a feeling almost like a bubble in my chest and it feels like my hearts beats faster in that moment, but I can't tell if it's just a feeling or my actual heart beating. It's strange and makes me panic each time. It also only happens when I'm laying down.

Is it when you are sleeping? Could be sleep apnea. If not, if my anxiety is rough, I cant lay on my back...it makes my breathing shallow and my chest gets tight.
