Julesy, My scan was exactly like yours. Heart beating really fast, like a white flashing light. My scan actually identified that there was a bleed and my DR wasn't concerned. Bad news is the ultrasound says I'm only 6 weeks! not 7! so I'm kind of disappointed about that. I know there could have been extremely worse news but I can't wait until the first trimester is over so I can be gone with feeling off and tell everyone!
