Overview
The common electrocardiographic findings that occur secondary to physiological changes during pregnancy include: tachycardia, short PR interval and left axis deviation.
Electrocardiographic Findings
- Physiologic hyperdynamic circulation may cause tachycardia with accompanied shortened PR interval.
- Left axis deviation attributed to horizontal position of the heart resulting from progressive uterine enlargement.[1]
- Non-specific ST segment depression and T wave flattening may be observed in a small percentage of pregnant patients. However, these changes resolve without further complications following delivery.[2][3]
