How many weeks of pregnancy should I do an electrocardiogram

After a woman becomes pregnant, she should do different types of tests purposefully according to the time of pregnancy. These tests, while ensuring the health of the woman, also test the health of the fetus. After the fetus has different types of fetal heartbeats and fetal movements, the methods of examination are more diverse. So, at how many weeks should the fetal electrocardiogram be done?

1. After 18 weeks. For most fetuses, the fetal heartbeat will become stable around 18 weeks of pregnancy. At this time, you can purposefully check the health of the fetus's internal organs. Fetal electrocardiogram is one of them. The fetal electrocardiogram performed at this time can also detect whether the fetus has congenital heart disease, ensuring the safety and health of the fetus.

2. 22 weeks. At 22 weeks of pregnancy, you are already in the second trimester. At this time, the fetus's internal organs are basically complete, the fetal electrocardiogram results will be more accurate, and the fetus's life state at this stage will be relatively stable. The woman's body burden will not be very heavy, and she can cooperate well with the doctor's examination.

3. After 12 weeks. If necessary, for example, if a woman has taken some medicines during pregnancy and has received some radiation during pregnancy, and is worried about affecting the baby's heart health, she can also discuss with her doctor to do a fetal electrocardiogram about 12 weeks after pregnancy. At this time, it can also be checked whether there is any abnormality in the fetal heart.

How many times should an electrocardiogram be performed during pregnancy?

Experts emphasize that electrocardiogram is one of the routine physical examination items during pregnancy, and an electrocardiogram is usually performed during the consultation and at 32-34 weeks of pregnancy.

It is generally recommended that pregnant women have an electrocardiogram during the face-to-face consultation, at 32-34 weeks of pregnancy, and before delivery. During the consultation, the main purpose is to understand the pregnant mother's heart function and rule out heart disease to determine whether the pregnant mother can bear childbirth. If there is a problem, she should go to the internal medicine department for immediate treatment.

In addition, the stress on the heart during pregnancy goes through two peak stages, namely at 32-34 weeks of pregnancy and when the pregnant woman gives birth. Blood flow increases in late pregnancy, reaching a peak at 32-34 weeks of pregnancy, an increase of 40%-45%, and the cardiac load increases; during delivery, the mother's blood is in a state of increased stasis, the venous circulation resistance increases, and some pregnant women are prone to heart failure or even decline. Therefore, it is best for pregnant mothers to do an electrocardiogram during these two time periods to check the heart pressure state.

An electrocardiogram refers to a graph (commonly known as ECG) of various potential changes that are induced from the skin by an electrocardiograph as the pacemaker, ventricles, and atria are excited successively during each cardiac cycle. Electrocardiogram is an objective indicator of the generation, propagation and recovery process of cardiac impulses. There are many symptoms that indicate abnormal ECG test results. Depending on the ECG test results, the suspected symptoms may also be different, such as angina pectoris, myocardial infarction, arrhythmia, ventricular premature beats, hypokalemia and other symptoms.
