The aim of this study was to assess cardiotocograph (CTG) interpretation by midwives and trainee obstetricians using the standard and a modified definition of fetal heart rate deceleration compared with consultant interpretation as the Gold Standard. A randomised survey using the online tool at: www.surveymonkey.com between 4 January and 24 April 2009, was conducted at a tertiary obstetric unit, UK. A total of 104 (∼54%) health professionals responded, providing 1,118 responses with respect to the presence of decelerations on 13 anonymised CTGs. Five obstetric consultants (62.5%) provided expert opinion. Midwives and trainee obstetricians were more likely to concur with Consultant opinion when using the modified definition of fetal heart rate deceleration compared with the standard definition. Larger scale studies may be needed to further evaluate the usefulness of the modified definition.

Fetal Circulation

Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...
Pulse rhythm01:30

Pulse rhythm

Pulse rhythm refers to the pattern of pulsations within specific intervals, offering valuable insights into the regularity or irregularity of the heart's beats as observed through the pattern of pulsation within specific intervals. A regular pulse exhibits a consistent heart rate with uniform waveforms and pulsation force, variations of which can be classified as normal, weak, or bounding.
Conversely, an irregular pulse pattern is termed dysrhythmia, stemming from disruptions in cardiac muscle...
ECG Interpretation of Rhythms01:24

ECG Interpretation of Rhythms

An electrocardiogram (ECG)graphically represents the heart's electrical activity on ECG paper or a monitor.
Components of the Electrocardiogram
The primary components of a normal ECG waveform in Normal sinus rhythm(NSR) include the P wave, PR interval, QRS complex, ST segment, T wave, and occasionally a U wave.
ECG waveforms are divided by vertical and horizontal lines at standard intervals.
The horizontal axis measures time and rate, and the vertical axis measures amplitude or voltage. When...
