Stroke or sleep paralysis?

Hello Everyone!

I’m a 32M with asthma, and I’m experiencing something quite strange and anxiety-inducing.

Just after falling asleep, I often feel like my heart is racing or about to burst out of my chest. It feels like I’m awake but also paralyzed, and after a short while, I wake up completely fine, with just a bit of tachycardia. It seems similar to sleep paralysis. This has happened several times with varying frequency, and it makes me very uncomfortable because I can’t tell if it’s really happening or if it’s just in my mind.

Additionally, less than a year ago, I had an ECG done, and everything was normal. The doctor only noted early repolarization. They also performed an imaging test on my heart (I’m sorry, I don’t remember the name), and the morphology was normal.

Has anyone else experienced something similar?

Thank you!
