Dec 13, 2025 · Marked variability in the fetal heart rate, defined as fluctuations exceeding 25 beats per minute, can be an early sign of acute hypoxic stress or umbilical cord compression. …

Marked variability in the baseline FHR is present when the amplitude exceeds 25 BPM.This pattern (sometimes called a saltatory pattern) suggests acute hypoxia or mechanical …

The variability is classified as absent, minimal, moderate, or marked. When the fetus is well oxygenated and has a normal acid-base balance, the FHR variability is typically moderate. …

The exposure was marked variability in fetal heart rate in the 60 minutes before delivery, with a minimum duration of 1 minute. The primary outcome was neonatal acidosis, defined as an …
