i am 34 weeks along and I have spent the last week in the hospital being monitored 24 hours a day because my baby girl has a heart rate that fluctuates between 220 and 235 and has accelerations that go up so high the machine can't track them. Her baseline has been about 220 and it has been pretty consistent. Everything else looks perfect. Her heart (other than the rate) is functioning perfectly, she is moving the way they want her too, and she is developing right on track. They are planning on delivering her next week just before I'm 36 weeks. Does anyone have an experience like this? The doctors seemed stumped and I'm obviously extremely concerned. Any insight would be great!
