So I've been having these spells every few days where my heart will start beating really fast and I get super light headed to the point where I feel I may pass out. It almost feels like when you've had too much caffeine or if you're having a panic attack which I have no history of panic attacks. It just started this past week and I didn't know if it was something that I needed to get checked asap or if it can wait till my appointment on Monday. If I just sit still and rest for a bit it helps for it to go away. No headaches or spots so I didn't worry about it being hypertension.

Any input is appreciated!
