Im 22 years old and recently suffered my first miscarriage. I went to the emergency room for food poisoning and was told my heart rate was 140. After receiving 3 liters of fluid, my heart rate would not decrease and an ultrasound revealed an underdeveloped embryo. A week later, another US detected no fetal heartbeat and I had a D&C. I was never told what caused the tachycardia. My question is, are the three (tachycardia, dehydration and miscarriage) somehow related?
Madam you have miscarriage sorry for that, what happened when any insult to any part of the body happened there is auto defense mechanism of the body which is activated itself. Then a systemic inflammatory response started which is compensated in the form of increased heart rate, sometime fever, increased or decreased blood pressure. Dehy Chat Doctor.  Miscarriage or abortion is the last thing to happen. Take Care
