fetal premature ventricular contraction

Fetal premature ventricular contractions (FPVC) are a type ectopic ventricular contractions detected in utero. They are a type of extrasystoles.

Premature ventricular contractions are often followed by a compensatory pause due to the refractory state of the conduction system; the next conducted impulse arrives at twice the normal interval, and the continuity of the rhythm is not broken.

Pathology

FPVC's can be associated with:

Prognosis

Most isolated FPVC's usually resolve spontaneously prior to delivery and those that persist into neonatal period usually resolve within 6 weeks. They can however rarely result in more complex arrhythmias (supraventricular tachycardia in 0.4-1% of cases).
