my daughter is very athletic, great shape, correct weight. She lost her period 2 months ago and thru all tests, is not pregnant. Doc gave her provera to jump start her cycle. After 2 pills, she noticed, thru her heart monitor that she wears for work outs, that her heart has episodes of 200 to 250 bmp then it drops to 60 or lower. Last episode lasted 20 minutes. No other symptoms? age 31, ht. 5 4 , weight 130 normal, but last 2 weeks pickup 8 to 10 lbs. Very bloated, taking natinal beta blocker because had a history of low blood pressure and high heart rate. But it has been under control for many years. She takes half a pill daily. Her pressure still normally reads slightly lower and heart rate is alway under 100. Today she has been reading error in her blood pressure machine at times, heart rate goes up to 250 at times, longest 20 minutes. When she can get a reading for her pressure it reads still 100 over 65-70 which is normally for her. Could the provera be causing this high heart rate episodes???
