NRFHT

Also written as: NRFHT — Non-Reassuring Fetal Heart Tracing

Non-reassuring fetal heart tracing: patterns indicating potential fetal compromise requiring intervention.

Full Definition

Non-reassuring fetal heart tracing (NRFHT) refers to fetal heart rate patterns that deviate from normal and suggest possible fetal hypoxia or distress. These patterns may include persistent tachycardia or bradycardia, decreased or absent variability, recurrent late decelerations, variable decelerations with concerning features, or prolonged decelerations. NRFHT patterns require careful evaluation and often prompt intervention such as maternal position changes, oxygen administration, fluid resuscitation, or expedited delivery. The interpretation of fetal heart tracings requires expertise as patterns can be influenced by factors such as fetal sleep cycles, maternal medications, or cord compression. The goal is to identify fetuses at risk for adverse outcomes while avoiding unnecessary interventions for benign variations.

Usage

Usage note: More specific than general term 'fetal distress'; focuses on heart rate patterns.

In Context

  • "NRFHT with recurrent late decelerations prompted preparation for emergency cesarean delivery." — Labor and delivery note
  • "The patient was counseled about NRFHT findings and options for continuous monitoring versus delivery." — Intrapartum consultation
