Expectant mothers perceiving a sudden decrease in fetal movements should not rely on fetal heart monitors at home to reassure themselves of their baby’s well-being according to Dr. Abhijoy Chakladar of Princess Royal Hospital in West Sussex, England.
Dr. Chakladar reports a case where a mother at 38 weeks, noticed a decrease in her baby’s movements, but was reassured by an apparent fetal heartbeat from her monitor. However, the device may have been detecting the mother’s heartbeat. A few days later, unable to hear the baby’s heartbeat, she went to the hospital where the fetus was discovered to be stillborn.
