I normally don't worry much about my heart- oddly enough my focus has been on neurological and gastric issues (gee- 2 things that the nervous system messes up with anxiety- go figure).
Anyway, I woke up out of a dead sleep last night at 4:30am by a bunch of heart palpitations (felt like a pounding in my chest and like my heart was skipping a beat or something). It took me awhile to fully wake up and to try and change my breathing pattern to make it stop. I realized that my nose was semi-clogged from allergies and I was half breathing out of my mouth and nose. I couldn't fall back asleep and it wasn't until I got up and took a claritin pill to open up my sinuses that my heart palps stopped. I don't know if it was my weird breathing or what....just wanted reassurance that this is normal. I don't need something else to stress out about. I have had the heart palps on and off through out the day today when my nose gets stuffy. Nothing like the hour and a half straight this morning, but this really came out of left field.
