CTG
Also written as: CTG — cardiotocography
Cardiotocography - continuous monitoring of fetal heart rate and uterine contractions during pregnancy and labor.
Full Definition
Cardiotocography (CTG) is a technical method of monitoring fetal wellbeing by simultaneously recording the fetal heart rate and uterine contractile activity. The trace provides information about fetal oxygenation status and is interpreted using standardized criteria including baseline rate, variability, accelerations, and decelerations. CTG monitoring may be intermittent or continuous and is routinely used during high-risk pregnancies and active labor. Interpretation requires understanding of normal patterns and recognition of pathological features that may indicate fetal compromise.
Usage
Usage note: Always capitalize as CTG; avoid confusion with other monitoring abbreviations like ECG.
