Overview

The common electrocardiographic findings that occur secondary to physiological changes during pregnancy include: tachycardia, short PR interval and left axis deviation.

Electrocardiogram

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 transient ST segment depression, T wave flattening and presence of Q wave may be observed in a small percentage of pregnant patients. However, these changes resolve without further complications following delivery.^[2]^[3]

Holter monitoring is advised for high-risk pregnant women with atrial fibrillation or other documented arrhythmic disorder.
