The main reasons for this are: firstly, if the symptoms of premature heartbeat occur only occasionally, it will not affect the delivery, and the relevant examination should be carried out before the delivery to see if there are any complications. Secondly, if the premature beats are more frequent and ventricular premature beats, the cause must be further investigated to see what factors are causing it, according to the patient’s physical condition, 24-hour ambulatory ECG or ultrasound of the pregnant woman’s heart can be done to understand the heart function of the pregnant woman. If the pregnant woman has poor heart function, it is best not to have a normal delivery, but to have a cesarean section under close monitoring to avoid accidents to the pregnant woman and the fetus, and to pay attention to detecting the maternal vital signs after surgery, and to control the amount and speed of infusion to avoid heart failure.
