what is category 1 fetal heart tracing?
12446
Category I : Normal. The fetal heart rate tracing shows ALL of the following: Baseline FHR 110-160 BPM, moderate FHR variability, accelerations may be present or absent, no late or variable decelerations, may have early decelerations. Strongly predictive of normal acid-base status at the time of observation.

At seven weeks, the embryo's heartbeat can be detected through an ultrasound scan. A heartbeat is the first sign of a healthy and live foetus. The mother's reproductive health is checked. Through an ultrasound scan at 7 weeks, twin or multiple pregnancy can be detected in the form of multiple gestational sacs.

A fetal heartbeat may first be detected by a vaginal ultrasound as early as 5 1/2 to 6 weeks after gestation. That's when a fetal pole, the first visible sign of a developing embryo, can sometimes be seen.

A Level 2 ultrasound is a comprehensive, detailed evaluation of fetal anatomy and development. It is a much more in-depth evaluation of the fetus than a standard or Level 1 ultrasound. The ultrasound examination is usually performed at about 20 weeks gestational age.

Fetal fraction describes the proportion of the total cfDNA that is fetal in origin. The 'fetal' component is actually derived from placental trophoblast (2, 3). Thus, cfDNA analysis (NIPT) for fetal trisomy can be considered a 'liquid biopsy' of the placenta.

FHHR. This stands for 'fetal heart heard regular', which means that the midwife or doctor has heard your baby's heart.

What is nonreassuring fetal status? Nonreassuring fetal status (NRFS) is a term that may be used to describe a baby's health late in the pregnancy or during labor. It is used when test results suggest that the baby may not be getting enough oxygen.

Hypoplastic left heart syndrome (HLHS) is a birth defect that affects normal blood flow through the heart. As the baby develops during pregnancy, the left side of the heart does not form correctly. Hypoplastic left heart syndrome is one type of congenital heart defect. Congenital means present at birth.

In the normal pregnancy, fetal heart motion (FHM) was observed with TVS in all the 43 cases (91.3%) where FP/fetus was seen, whereas in comparison with TAS, FHM was seen in 32 cases (69.6%).

In fetal circulation, the right side of the heart has higher pressures than the left side of the heart. This pressure difference allows the shunts to remain open. In postnatal circulation, when the baby takes its first breath, pulmonary resistance decreases and blood flow through the placenta ceases.

Background. The AHA recommends a fetal echocardiogram in all in-vitro fertilization (IVF) conceived pregnancies citing increased rates of congenital heart defects (CHD) in this group.

FHT. Abbreviation for fetal heart tones , under tone.

One that has been around for decades, and has even gained some acceptance, is the idea that fetal heartbeat is faster among girls. Rates above 140 beats per minute, it is said, are typical for girls; below that, look for a boy.
265439
The normal fetal heart rate is between 120 and 160 beats per minute. Typically, an abnormally fast heart rate is over 200 beats per minute.

A deceleration is a decrease in the fetal heart rate below the fetal baseline heart rate. An early deceleration is defined as a waveform with a gradual decrease and return to baseline with time from onset of the deceleration to the lowest point of the deceleration >30 seconds.

How an NT screening is done. An NT is a special type of ultrasound using a highly sensitive ultrasound machine. A sonographer will first measure your baby from crown to rump to ensure that the fetal age is accurate. Then he or she will locate the nuchal fold and measure its thickness on the screen.

Fetal surveillance consists of a number of tests used to assess the health of babies in the womb, and has been a part of obstetric care since the 1970s. ... This may be detectable as fetuses generally respond to a lack of oxygen with certain physiological changes, such as altered heart rate and movement.
