Hi everyone,
The past couple nights I've noticed that when I wake up and roll over, my heart will beat super fast and hard in my throat/upper chest for about 6-12 beats and then settle down. It's only when I've awoken from sleep and I don't notice it during the day, just a bit frightening to feel.
Does it sound like a flutter or palpitation? I feel completely fine when it happens and go back to sleep after it settles down.
