Many different kinds of signs and symptoms appear related to the heart during pregnancy. However they are physiological and considered normal They can vary from fatigue, fainting shortness of breathing, chest pain, lack of sleep, palpitations, and even heart murmurs.

Heart murmurs usually occur due to an increased rate of blood flow to the heart throughout pregnancy. They can be because of an increased volume of blood that is flowing through the heart or are any underlying problems related to heart that may be a perfectly normal thing but you need to consult a doctor for expert opinion so that he can differentiate whether they are physiological or pathological murmurs.

Systolic murmurs occur during pregnancy. These murmurs are caused by an increase in the blood flow through the right and left ventricle. They can be 1 by 6 or 2 by 6 midsystolic murmurs that do not radiate anywhere. On auscultation, however diastolic Murmur is not very commonly found during pregnancy.;

Women can have a healthy pregnancy even if they have murmurs. Heart murmur is just an added sound that can be heard during pregnancy and it is very common. This type of murmurs goes away by themselves after delivery.

What About Your Babys Heart Rate

The heart rate of a fetus normally varies between 120160 beats per minute. As your baby moves around in the womb, some irregularity in heartbeat is normal. It is also common in the second trimester as your babys heart matures. However, if the irregularity persists, medical intervention will be required. Your doctor will monitor this during pre-natal checkups. According to experts, excessive caffeine consumption, say, more than a cup of coffee a day, can cause irregularities in your babys heart rate, so cut down or avoid altogether.

In a majority of cases, irregular heartbeats in babies resolve on their own. But, sometimes, it can be indicative of a structural abnormality of the heart or other problems. Your doctor will monitor the heart rate of your baby, investigate its cause, and prescribe medication or take other steps to ensure the well-being of your baby.12

Finding A Good Sleeping Position

Early in your pregnancy, try to get into the habit of sleeping on your side. Lying on your side with your knees bent is likely to be the most comfortable position as your pregnancy progresses. It also makes your heart’s job easier because it keeps the baby’s weight from applying pressure to the large vein that carries blood back to the heart from your feet and legs.

Some doctors specifically recommend that pregnant women sleep on the left side. Because your liver is on the right side of your abdomen, lying on your left side helps keep the uterus off that large organ. Sleeping on the left side also improves circulation to the heart and allows for the best blood flow to the fetus, uterus, and kidneys. Ask your doctor what he or she recommends.

But don’t drive yourself crazy worrying that you might roll over onto your back during the night. Shifting positions is a natural part of sleeping that you can’t control. Most likely, during the third trimester of your pregnancy, your body won’t shift into the back-sleeping position anyway because it will be too uncomfortable.

If you do shift onto your back, the discomfort will probably wake you up. Talk to your doctor, who may suggest that you use a pillow to keep yourself propped up on one side.

And eventually, after delivery, this cardiac output decreases rapidly first and then starts increasing gradually and it returns to the pregnancy level;6 weeks later after the delivery.

We asked our expert family GP Philippa Kaye if tracking a higher heart rate can really reveal if youre pregnant and she agrees that yes, a higher heart rate is experienced by all women when theyre pregnant, but unless youre using a heart rate monitor, you just wont notice.

    Heart Rate And Blood Pressure Changes During Pregnancy Are Less Dramatic Than Previously Thought

    How often are heart palpitations benign during pregnancy?

    New analysis from over 36,000 healthy women in 20 countries suggests that physiological changes during pregnancy may not be as dramatic as traditionally taught. However, average blood pressures do appear to be increasing year on year.

    Medical text books are based on data that is now over forty years old. New research from researchers at The University of Oxford, and published in BMC Medicine, includes much more recent data. The new findings show that changes to womens blood pressure and heart rate during pregnancy are not as striking as previously thought.

    Traditionally, medical text books have taught students that blood pressure drops by 10-15mmHg during the middle of pregnancy. These text books are based on old data and quite small numbers of pregnant women. This newer and much larger analysis shows that the lower diastolic blood pressures seen mid-pregnancy are on average just 1-2 mmHg lower than the earliest measurements that were taken in about week 10. This is much less of a drop than suggested in the text books. The analysis also shows that, on average, systolic blood pressure rises very slightly through pregnancy.

    Blood pressure in pregnant women has increased slightly each year since 1967. The steady increase in blood pressure over time since 1967 may be a result of pregnant women being older and heavier. Blood pressures are similar for those women pregnant with their first baby as for those who already have children.

    How Does Pregnancy Affect Your Heart Rate

    During pregnancy, your body undergoes several changes to rise to the occasion of caring for and giving birth to a healthy baby. Some of these changes, like the enlargement of your breasts, are visible. However, other parts of your body are also quietly adapting to the changing demands of your body as you carry a baby. Your cardiovascular system is no exception. Your heart now needs to work harder since more blood needs to be pumped to the uterus as your baby grows. Lets take a look at what this means for your heart rate.

    What Is A Target Heart Rate

    Your heart rate is the speed at which your heart beats. It beats slower when you are resting and faster when you exercise. Because of this, you can use your heart rate to measure the intensity of your exercise. For every age group, there is a target heart rate. The target heart rate is the rate your heart beats during good aerobic exercise. By monitoring your heart rate and comparing it to your target range, you can determine whether you are exercising too hard or not hard enough. When you exercise, you should aim to reach your target heart rate and stay within that range for 20 to 30 minutes.

    You can measure your own heart rate by taking your pulse. To do so, place your index and middle fingers on the wrist of your other hand, just below your thumb. You should be able to feel a pulse. Count the heartbeats for 60 seconds. The number you count is your heart rate, in beats per minute. You can also purchase a digital heart rate monitor to keep track of your heart rate for you.

    You can find the target heart rate for your age from the American Heart Association website.

    How An Activity Tracker Caught An Unexpected Pregnancy

    Fitness trackers, by nature of being worn around the clock, have the potential to capture unexpected insights about how your body works and simplify laborious acts like manually figuring out your fertile days. That traditionally involves taking your temperature when your body is at rest, examining your cervical mucus, and recording this data every single day on a calendar.

    Clues study, which ran for 13 months beginning in April 2015, didnt set out to see whether the Fitbit ChargeHR could identify when a woman becomes pregnant. Rather, it was exploring whether the device could reliably track an already-known occurrence: how a womans resting heart rate changes when shes experiencing rising hormonal levels linked to ovulation.

    For the experiment, five women under 40 wore a Fitbit ChargeHR to bed. Thats because resting heart rate data can be captured at its purest when a person is asleep and not moving. The women also logged their periods on Clues app, and took daily urine tests to track when there was a surge in the key hormones that signaled they were entering ovulation.

    Researchers were watching all these biometrics as the study participants went through their cycles. A womans fertile window when shes likeliest to get pregnant usually occurs two weeks after the start of her last period, and lasts for about six or seven days, ending on the day of ovulation.
