An ECG is perfectly acceptable during pregnancy and has no impact on the health of the pregnant woman or the fetus. ECG is a technique that uses an electrocardiogram machine to record from the surface of the body the graphical representation of the changes in the electrical activity of the heart during each cardiac cycle. The ECG machine is not radioactive and does not produce any radiation effects on the human body. Therefore, it is possible to have an EKG during pregnancy without any adverse effects on the pregnant woman or the fetus. The ECG is mainly used to check the heart function of the pregnant woman for arrhythmias and conduction blocks, as well as other diseases of the heart function, which can be displayed on the ECG machine. During pregnancy, an ECG is performed as a routine test and should be done with as much confidence as possible.
