Fetal premature atrial contractions
Updates to Article Attributes
Body
was changed:
Fetal premature atrial contractions (FPAC's)are a type of extrasystoles that can be occasionally detected in fetal heart monitoring. They along with fetal premature ventricular contractions (PVC's) account for the majority of in utero rhythm disturbances3
PathophysiologyPathology
They may arise from immaturity in the fetal cardiac conduction system 2. The conductions arise in the atrium and can be either transmitted to the ventricles or blocked.
Associations
- in
~11-2% of cases, they can be associated with a congenital cardiac anomaly
Significance
They are benign and usually self-limiting and do not generally compromise cardiac function. In most cases, they disappear spontaneously in utero.
