Just lately I have been getting these heart flutters and I get sorta breathless , feel tired have to take a deep breath. It doesnt happen all the time but throughout the day more then 5 times. I am 62 this year, I was diaignosed with anxiety attacks when I was 50. Went to counseling have been ok ever since, But at that time my heart started doing that fluttering and my naturepath had me take COQ10 200mg a day, which after 3 days it was gone. I'm under some stress with family etc. no more then most. Is that why it does it??
