Overview
Heart rate variability (HRV) provides a non-invasive assessment of autonomic control of the nervous system over the heart. During pregnancy, the cardiovascular system adapts significantly, affecting HRV and hemodynamics. Studying the relationship between HRV and hemodynamic changes is critical to understanding and monitoring cardiovascular health during pregnancy and postpartum, and predicting potential complications.
