Normal ECG data for pregnancy, which may partially relate to changes in the position of the heart, include:
- Atrial and ventricular ectopic rhythms.
- Q-wave (small) and inverted T-wave in lead III.
- Depression of the ST segment.
- Shorter than normal, PR interval.
- Inversion of the T-wave in the lower and lateral directions.
- Shift to the left of the QRS.
- The electric axis of the heart is turned to the left.
- The heart rate is higher than normal.
