Fetal atrial fibrillation is a type of fetal tachyarrhythmia and usually has atrial rate of 400 beat per minute and a completely irregular ventricular rhythm.
Antanatal ultrasound - echocardiography
The artial contractions are usually too faint to be detected by M Mode ultrasound. An irregular ventricular rate may be detected.
