Fetal Cardiac Arrhythmia

    It is not usual for the fetus to have an irregular heart beat (cardiac arrhthmia) during pregnancy. More often than not it is a benign condition, though it requires further tests when it is observed. There are several different arrhythmias, and most pose no problem to the fetus:

    Simple Arrhythmias:

    • Premature atrial contraction (PAC)
    • Premature ventricular contraction (PVC)
    • Sinus tachycardia (ST)
    • Sinus bradycardia (SB)
    • Premature atrial contraction blocked

    Potentially Fatal: 

    • Atrioventricular block (A-V) 
    • Supraventricular tachycardia (SVT)
    • Atrial flutter (AF)
    • Nodal tachycardia
    • Complex arrhythmias
