What Is The Outlook For Neonatal Arrhythmia

Newborn Infant Heart Rate Assessment | Pediatric Nursing Skill

The outlook for babies born with arrhythmia depends primarily on the type of rhythm difference theyre experiencing. It also depends on how early doctors diagnose and manage the arrhythmia.

A 2022 study suggests that, compared with infants with benign arrhythmias, babies with non-benign arrhythmias have higher rates of recurrence and mortality.

However, a report by the Pediatric Cardiac Intensive Care Society suggests that with early diagnosis and the right treatment at the outset, you can avoid many life threatening events and good quality of life can be possible.

The report also notes that short- and long-term care for a child with an arrhythmia may require several different treatments, including medications, implanted devices, and surgery or cardiac catheterization.

What Is A Healthy Heart Rate For A Child

When your child is sitting quietly, their heart rate is considered a resting heart rate. A healthy resting heart rate can vary by age.

  • Newborns 0 to 1 month old: 70 to 190 beats per minute
  • Infants 1 to 11 months old: 80 to 160 beats per minute
  • Children 1 to 2 years old: 80 to 130 beats per minute
  • Children 3 to 4 years old: 80 to 120 beats per minute
  • Children 5 to 6 years old: 75 to 115 beats per minute
  • Children 7 to 9 years old: 70 to 110 beats per minute
  • Children 10 years and older: 60 to 100 beats per minute

It’s likely that your child’s pulse stays within these healthy ranges, even if the pulse feels very fast. Understanding the variations in heart rates and how to properly check your child’s rate can help keep track and prevent unnecessary concern.

Why You May Not Hear Fetal Heartbeat In An Early Ultrasound

You may not be able to hear the heartbeat if the scan is too early in your pregnancy. In such a case your doctor will reschedule another scan in one to two weeks. Other reasons could be:

  • The method your sonographer uses to listen to the heartbeat. Transvaginal ultrasound gets better results compared to hand-held dopplers
  • The accuracy of dates, when you are not sure about the last menstrual date or had irregular ovulation
  • Highly active baby that keeps moving around the womb, blocking the view
  • Fetal position in the womb
  • Gestational age

If there are no issues, you will be able to hear it clearly. However, the heart rate of the baby is not usually steady and may change as the pregnancy progresses.

The hospital staff takes other measurements of each baby. These include:

  • Head circumference. The distance around the baby’s head.

  • Abdominal circumference. The distance around the belly .

  • Length. The measurement from top of head to the heel.

The staff also checks these vital signs:

  • Temperature. This checks that the baby is able to have a stable body temperature in normal room.

  • Pulse. A newborns pulse is normally 120 to 160 beats per minute.

  • Breathing rate. A newborns breathing rate is normally 40 to 60 breaths per minute.

What Are The Signs And Symptoms Of Neonatal Supraventricular Tachycardia

Neonatal supraventricular tachycardia can develop before birth , while the baby is developing in the womb. If it occurs prenatally, there can be an abnormal build-up of fluid in the babys body, which can become life-threatening if not diagnosed and treated promptly.

After birth, the symptoms of neonatal SVT occur in episodes, which can last for a few seconds to a number of hours. Many babies will not show any specific symptoms but will seem generally unwell. They may look pale, feed poorly or vomit and may not be as alert as usual. If the episodes continue into childhood, symptoms can include heart flutters, shortness of breath, dizziness and chest pain.

What Are The Risks Of Fetal Heart Monitoring

Radiation is not used for this test. The transducer usually causes nodiscomfort.

You may find the elastic belts that hold the transducers in place slightlyuncomfortable. These can be readjusted as needed.

You must lie still during some types of fetal heart rate monitoring. Youmay need to stay in bed during labor.

With internal monitoring, you may have some slight discomfort when theelectrode is put in your uterus.

Risks of internal monitoring include infection and bruising of your babysscalp or other body part.

Note:You should not have internal fetal heart rate monitoringif you are HIV positive. This is because you may pass the infection on toyour baby.

You may have other risks depending on your specific health condition. Besure to talk with your provider about any concerns you have before theprocedure.

Certain things may make the results of fetal heart rate monitoring lessaccurate. These include:

  • Obesity of the mother
  • Position of the baby or mother
  • Too much amniotic fluid
  • Cervix is not dilated or the amniotic sac is not broken. Both of these need to happen to do internal monitoring

Is Babywearing Safe For Newborn

Is Baby Wearing Safe? The biggest concern with baby wearing is suffocation, especially for babies under 4 months old. Babies dont have very good head control for the first few months after birth because of weak neck muscles. If your babys mouth and nose become obstructed, they wont be able to breathe.

Other Causes Of A High Heart Rate

Sometimes the culprit behind a childs fast heart rate is much easier to fix.For example, one controllable factor is caffeine. A child may develop a high resting heart rate if they consume coffee, energy drinks, or several sodas throughout the day.

The side effects of some medications can also affect a child’s resting heart rate. While you might expect that a stimulant for ADHD might raise your child’s heart rate, you may be surprised to learn that an over-the-counter decongestant can do so as well.

A high resting heart rate can also be associated with pain, dehydration, or a fever. If the high heart rate is attributed to these factors, the reversal of those conditions should bring the heart rate back to normal.

A child who is sick with a high fever may have a high heart rate, and treating the fever with a fever reducer should bring the heart rate back to the normal range.

Ultrasound And Congenital Heart Defects

What are normal heart rates and breathing rates for children?

Your first prenatal ultrasound, which is scheduled sometime between the 6th and 9th week, confirms your pregnancy, determines due date and monitors the heartbeat. Considering that nearly 1% of births every year are known to have congenital heart defects, the doctor observes the structure of the heart to check for any congenital disabilities in the second ultrasound, or the 20th-week anatomy scan .

Though there is no treatment in utero, it helps the doctors decide when and how to deliver the baby. Most congenital issues are corrected after the babys birth, either through surgery or medications. If there is a problem with the fetus heart rhythm, your doctor may suggest medications to decrease the risk of complications in the baby.

If you are anxious to listen to your babys heartbeat, check with your doctor about it. If there are any concerns with the heart rate, it will be monitored closely through the pregnancy. But if you want to monitor it at home, talk to your doctor first.

How To Keep The Babys Heart Healthy

Besides the factors mentioned above, genetic or chromosomal abnormalities also cause the babys heartbeat to fluctuate. Here are a few ways to keep the babys heart healthy and the heart rate ideal.

  • Take folic acid supplements as they help in lowering the probability of congenital heart defects in the baby.
  • Quit smoking as early pregnancy smoking is known to cause 2% of heart defects, including anomalies of valves and vessels, in babies.
  • Manage your gestational diabetes by taking the right medications and steps to control the blood sugar levels.
  • Do not take alcohol or drugs.
  • Avoid using Accutane for acne when you are pregnant, as it can cause fetal heart issues.

While you do this, you may also want to check or monitor your babys heart rate at home, using a heart rate monitor.

How Can I Check My Child’s Heart Rate

Measuring your child’s pulse is easy. There are several places on the body where you can check the pulse including the wrist, inside the elbow or the side of the neck. For most parents, the wrist is the easiest, most accessible place. To check your child’s heart rate, place two fingers on their wrist, below their thumb. Apply gentle pressure until you can feel a slight beat against your fingertips. Count how many beats you feel in 15 seconds. Then multiply that number by 4 to determine your child’s heart rate, which is measured in beats per minute.

For instance, if you feel 20 beats in 15 seconds, your child’s heart rate is 80 beats per minute, a normal rate.

However, you may not be able to easily find a pulse in infants or younger children who have smaller blood vessels. A medical professional with experience in caring for children will likely need to take their pulse.

“If you’re not familiar with taking a pulse, it may take a few tries until you become more comfortable and confident,” says Dr. Kane. “The best thing to do if you are concerned is to have a person with medical training check it for you.”

If your child has a heart condition requiring heart rate monitoring, your doctor can teach you how to find their pulse and take their heart rate. Some wearable devices and smartphones can also read the heart rate with good accuracy.

What Causes Arrhythmias

A unique electrical conduction system in the heart causes it to beat in its regular rhythm.

The conduction system of the heart is similar to the wiring of a light switch to a light:

  • The signal for the heart to beat comes from a place in the heart called the sinus node . The sinus node controls how quickly or slowly the heart beats. The sinus node normally speeds up the heart rate in response to things like exercise, emotions, and stress, and slows the heart rate during sleep.
  • The signal then travels from the sinus node down the wires to a resistor that helps control the signal, called the AV node. From there, the signal travels through the heart to tell it to pump.
  • But sometimes the electrical signals are abnormal, and the heart can start beating in a different rhythm this is an arrhythmia .

    Arrhythmias also can be due to chemical imbalances in the blood infections diseases that irritate the heart medicines injuries to the heart from chest trauma or heart surgery use of illegal drugs, alcohol, or tobacco caffeine and stress.

    Arrhythmias can be temporary or permanent. An arrhythmia can be congenital or can develop throughout life.

    What Is An Arrhythmia

    fetal heart rate monitor interpretation

    An is an abnormal heartbeat. The heart normally beats in a regular rhythm, but an arrhythmia can make it beat too slowly, too quickly, or irregularly. This erratic pumping can lead to a variety of symptoms, including tiredness, dizziness, and chest pain.

    Many arrhythmias don’t need medical care, but some can pose a health problem and need to be checked and treated by a doctor.

    Babys Heart Rate During Pregnancy

    Your doctor will check your babys heart rate. During pregnancy, it is possible for you to feel the heartbeat yourself and you can measure it too. It certainly feels great to hear the heartbeat, but it is natural to worry about your babys health when you notice low or high fetal heart rate . Here is a chart to help you understand more about baby heart rate during pregnancy:

    Size/Age of the Fetus

    120 to 180, with average of 150

    After week 12

    120 to 160, with average of 140

    How audible the heartbeat usually depends on the position of your baby as well as the nature of your abdominal tissues. Generally speaking, a fetal heart rate between 100 and 160 is considered normal, and a normal heartbeat lowers chances of miscarriage.

    Can Your Babys Heart Rate Predict the Gender?

    No, it is not possible to check your babys heartbeat to predict the gender. Some women say that it is a boy if the heart rate is over 140 bpm and it is a girl if the heart rate is below 140 bpm. This is among many old wives tales associated with pregnancy.

    What Are Vital Signs

    Vital signs include heart rate, respiration , blood pressure, and temperature. Knowing the ranges for vital signs for your child can help you notice problems early or relieve concerns you may have about how your child is doing. The table below includes information that can help.

    Centiles Of Normal Respiratory Rate

    The 1st to 99th centiles of respiratory rate in normal children from birth to 18 years of age are displayed in Figure 2. These demonstrate the decline in respiratory rate from birth to early adolescence, with the steepest decline apparent in infants during the first two years of life. The median respiratory rate decreases by 40% in these two years . Web Table 4 presents the proposed cut-offs for respiratory rate at each of 13 age groups from birth to 18 years of age.

    The subgroup analysis of the respiratory rate data showed no significant differences based on the type of study setting , level of economic development of the country in which it was carried out , wakefulness of the child , or whether manual or automated methods of measurement were used . Regression analysis on the dates of publication did not show any significant difference in measured respiratory rate .

    Why Might I Need Fetal Heart Monitoring

    Fetal Heart Rate Patterns: Normal and Abnormal Findings, VEAL CHOP – Maternity Nursing – L& D

    Fetal heart rate monitoring is especially helpful if you have a high-riskpregnancy. Your pregnancy is high risk if you have diabetes or high bloodpressure. It is also high risk if your baby is not developing or growing asit should.

    Fetal heart rate monitoring may be used to check how preterm labormedicines are affecting your baby. These are medicines are used to helpkeep labor from starting too early.

    Fetal heart rate monitoring may be used in other tests, including:

    • Nonstress test. This measures the fetal heart rate as your baby moves.
    • Contraction stress test. This measures fetal heart rate along with uterine contractions. Contractions are started with medicine or other methods.
    • A biophysical profile. This test combines a nonstress test with ultrasound.

    Things that may affect the fetal heart rate during labor:

    • Uterine contractions
    • Pushing during the second stage of labor

    Your healthcare provider may have other reasons to use fetal heart ratemonitoring.

    When To See A Doctor

    If a higher heart rate is a result of being under stress or consuming a lot of alcohol or caffeine, thats not typically a cause for alarm. However, these situations still warrant a discussion with your clinician, as they can discuss with you how to best address any necessary lifestyle changes.

    Meanwhile, adults without an acute condition that might cause an elevated heart rate may also want to contact their doctor if their resting heart rate remains above 100 beats per minute for a few days, says Dr. Tilahun.

    If the heart rate is persistently elevated for more than a few days and there is absence of a clear thing that can explain it, that should be a time to talk to your doctor, he says.

    Other Fetal Heartbeat Monitor Noises

    Your fetal doppler will also pick up noises other than a heartbeat, like placenta. Its essential to differentiate this noise from your babys heartbeat. One way to do this is to pay attention to the sound. For example, many describe the sound of placenta as a whoosh while a fetus heart is comparable to galloping horses.

    Another way to tell whether youve picked up a heartbeat is to look at the fetal doppler heart rate displayed on the screen. If it displays between the typical range of a fetus, its likely your probe is on the right spot.

    What Abnormal Results Mean

    Resting heart rates that are continually high may mean a problem. Talk to your health care provider about this. Also discuss resting heart rates that are below the normal values ( bradycardia

    A pulse that is very firm and that lasts for more than a few minutes should be checked by your provider as well. An irregular pulse can also indicate a problem.

    A pulse that is hard to locate may mean blockages in the artery. These blockages are common in people with diabetes or hardening of the artery from high cholesterol. Your provider may order a test known as a Doppler study
