I have been noticing something that the doctors seemed to want to ignore. Most of my symptoms of syncope/near syncope are when I stand up (especially after sleeping), bend over, going up stairs, reaching up high to get something.
My heart will thump really hard, or beat really fast during the syncope episodes.

Today I decided to wear my exercise heart rate monitor to see my heart rate when I did these things. When laying I waited for my HR to dip to low 60s-mid 50s, then stood up, and my HR would spike to around 100-110 before dropping back down. A spike of 35bpm and I feel the symptoms, while a spike of 45 and I feel a near blackout.

I was told in the hospital that the HR spike was normal, nothing is wrong with that. The explanation was because my HR rises, that rising was normal, that HR dropping when standing would be a bad thing.
This seems to contradict what I read online, so I am wondering if a HR spike of 35-50 bpm really is normal range.
