Fetal Supraventricular Tachycardia
4-chamber with sweep. Towards the end of the clip, one may appreciate the higher rate (SVT)
Fetal SVT. The atriums and corresponding ventricles are contracting at the similar rate and rhythm.
M-Mode through the RVOT, Aorta and Left Atrium during a fetal SVT event.
M-mode with 1 to 1 conduction. one may follow the aortic valve opening and closure - indicating systolic ejection time of the left ventricle (in normal great vessels configuration). The left atrial m-mode indicate atrial contraction with 1:1 conduction (Aortic valve opening and RV contraction).
Arch view in colour and 2D with signs of higher rate at which ventricular contraction and ejection occur.
