If fetal tachycardia requires medical treatment, doctors will discuss how the diagnosis and treatment may affect a baby’s delivery. Mothers often require admission to the hospital to monitor maternal and fetal response to the medication. These medications are given to pregnant mothers and pass to the fetus through the placenta. Fetal tachycardia is treated with medications that lower fetal heart rate. Other types of fetal tachycardia may need regular monitoring and treatment. Sinus tachycardia, for example, may not require treatment. Some types of fetal tachycardia resolve on their own. Myocarditis-an inflammation of the heart muscle.Congenital long QT syndrome -a heart signaling problem present at birth.Ventricular tachycardia also has been connected to: Ventricular tachycardia is caused by a problem with the electrical signal in the lower chambers of the heart (ventricles). SVT is caused by a problem with the heart’s electrical system.Ītrial flutter is caused by a problem with the electrical signal in the heart’s upper chambers (atria). Stimulants (drugs that speed up activities in the body).Fetal anemia (reduced oxygen in the blood).Excessive thyroid hormone secretion by the mother (maternal hyperthyroidism).The causes of fetal tachycardia vary by type. Ventricular tachycardia occurs when the heart’s lower chambers (ventricles) beat faster than the upper chambers (atria). This condition most often occurs in a structurally normal heart. Atrial FlutterĪtrial flutter occurs when the heart’s top chambers (atria) beat much faster than its lower chambers (ventricles). SVT occurs when the heart’s upper chambers (atria) and lower chambers (ventricles) beat faster than 200 BPM. Supraventricular tachycardia is the most common type of fetal tachycardia. During sinus tachycardia, the fetal heart is working normally but beating slightly faster than it should. Sinus tachycardia occurs when a fetal heart rate is above 180 BPM but less than 200 BPM. There are four types of fetal tachycardia. Fetal tachycardia complications include a dangerous form of fluid buildup called hydrops fetalis. For some, however, fetal tachycardia may require treatment. Fetal heart rate goes above 180 BPM at timesįetal tachycardia is rare.Fetal tachycardia occurs when a fetus (developing baby) has a heart rate faster than 180 beats per minute (BPM).ĭoctors may diagnose fetal tachycardia if: Fetal tachycardia is a type of irregular heartbeat known as fetal arrhythmia.
