HI, I have been experiencing heart flutters off and on for many years. Blood work all normal. I am 59 yrs old, female with hx of total hysterectomy in 2007. Headaches now for 3 weeks, back of head and side of head, feels like migraine but not seeing the usual light patterns. Have had a-fib in emergency room and have had ekg moniter for home. Had an ultrasound done for heart all seems normal. The heart flutters are horrible and put me in a instant bad mood, feels like heart is straining.
