I've beennoticing that once in a while when I gulp down water very fast
after a meal(like cold water) I get one ectopic beat. Like I can feel it in my throat.
I'm on those days extremely exhausted from lack of sleep.
Could it be that? Could it be that my vagus nerve is super sensitive due to lack of sleep and also dehydration that the large volume of water agitates it and maybe it's inflamed due to anxiety/stress and so the water excited it and that excited the heart.
It only happens with cold water, never with food or solid stuff
Thanks.
