What to do if a pregnant woman has sinus tachycardia

We all know that a woman's body will undergo some changes after she becomes pregnant. Especially as the pregnancy months continue to increase and the belly becomes bigger, it is particularly easy to have some symptoms. Among them, sinus tachycardia in pregnant women is the most common symptom among pregnant women. The occurrence of such symptoms always makes many pregnant women particularly worried, fearing that it will affect the growth and development of the fetus. Let us now understand what to do if pregnant women have sinus tachycardia.

What to do if a pregnant woman has sinus tachycardia:

But if this phenomenon has only occurred since you became pregnant, don't worry. The doctor has done a comprehensive examination for you and proved that there is no problem with your body. As the gestational age increases, the burden on the expectant mother's heart will continue to increase, and her heart rate will naturally become faster. In addition, the weakening of the body after pregnancy will also cause the heartbeat to accelerate, which is more obvious for mothers who did not like to exercise before. These are not reasons to worry about. Just pay attention to regular pregnancy checkups and do some proper exercise, and things will improve slowly.

Causes of sinus arrhythmia include:

There are many causes of sinus arrhythmia, both pathological and non-pathological.

The first cause of sinus arrhythmia is respiratory sinus arrhythmia. Its occurrence mechanism is that during the breathing process, the tension of the vagus nerve and sympathetic nerve in the body changes, causing the autonomy of the sinoatrial node to change periodically and regularly. When you inhale, the sympathetic nerve tone increases and the heart rate increases. When you exhale, the vagus nerve tone increases and the heart rate slows down. The cycle of changes in heart rate is exactly equal to one breathing cycle, and the heart rhythm becomes regular when breathing stops. This type of arrhythmia generally occurs in children, young people and the elderly and is a normal physiological phenomenon.

The second cause of sinus arrhythmia, that is, the cause of non-respiratory arrhythmia, is not very clear. Some people believe that it is related to anger, emotional instability, or the use of certain drugs (such as digitalis, morphine, etc.).

The third cause of sinus arrhythmia is sinus arrhythmia related to ventricular contraction and blood ejection. It is induced by abnormal ventricular contraction and blood ejection, which leads to uneven blood supply to the sinus node, thereby causing changes in the autonomy of the sinus node.

The fourth type is sinus arrhythmia induced by ectopic heart rhythm. Ectopic excitation, especially ectopic excitation originating from the atrium, can sometimes cause the sinoatrial node to be excited prematurely, followed by inhibition of the sinoatrial node, thus causing sinus arrhythmia induced by transient ectopic excitation.

After understanding what to do if pregnant women have sinus tachycardia, we know that sinus tachycardia in pregnant women is a normal phenomenon, but in order to ensure that it does not affect the health of the fetus, we must go to the hospital for examination and confirmation. If pregnant women have this phenomenon, they must go to the hospital regularly for fetal heart monitoring, and also pay attention to fetal movements. If the fetal movement is abnormal, go to the hospital for examination in time.
