for pregnant women passing electrocardiography (ECG, EKG) is not less important than the delivery of ultrasound tests or procedures.This study usually takes place when placing women at antenatal clinics, but may be repeated in the presence of medical indications or complaints of the pregnant woman.
ECG pregnancy performed to monitor the condition of the heart for the timely detection of any faults in his work, as well as in the development of preeclampsia in pregnant women (late toxicosis).If there are deviations from the normal condition of the woman requires supervision by a cardiologist.
Usually, in normal pregnancy, no significant changes in the electrocardiogram is not detected.There may be some changes in the circulation, as well as a slight displacement of the heart that appears on the ECG as the displacement (deformation, flattening) of the teeth and the cardiac electrical axis shift to the left.
Healthy woman during pregnancy is usually sinus heart rate, but may be shorter bouts of t
during childbirth, especially during labor and attempts, there is a reduction of the complex QRS (normal - from 0.04 to 0.11 s), the width of the P wave and the duration of the interval P Q, there is a deviation of cardiac electrical axis to the right.Also during labor (in some women - for a few days after birth) is disturbed heart rhythm - there are conditions such as atrial and sinus tachycardia, atrioventricular block, atrial rhythm, atrial or ventricular premature beats and others.Besides cardiac arrhythmias, during childbirth in women may develop sinus bradycardia (when the heart rate is less than 60 times per minute), sinus block, the rhythm of the coronary sinus, Parkinson's syndrome.
Timely ECG pregnancy is very informative as a method of predicting the course of pregnancy, and successful completion of delivery.
