fetal tachycardia causes
Causes And Symptoms Of Fetal Tachycardia. Fetal tachycardia is a condition which is characterized by heart rate higher than 160 beats per minute. Maternal fever leading to maternal ketosis is one of the leading factors. Dehydration or anxiety in the mother can also lead to fetal tachycardia.
Fetal bradycardia is usually diagnosed when the ventricular rate is <110 bpm. The most common cause of fetal bradycardia is sinus bradycardia, which can occur with vagal stimulation as is believed to occur with compression during ultrasound examinations, with fetal distress or with more serious systemic disease.
