Overview

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

Electrocardiographic Findings

  • Left axis deviation attributed to horizontal position of the heart resulting from progressive uterine enlargement.[1]
