It’s quite an exciting time to be at the forefront of Prenatal Care like we are within the PX Docs Network! In the past few years, we’ve not only seen more and more research prove how important neurological health is during the prenatal journey (for both mom and baby), but also, some incredible technology has been developed to help us track and measure your neurological health all along the way in just a matter of minutes!
This technology is called HRV, which stands for Heart Rate Variability, and it is an absolutely essential exam for all pregnant women to take on a regular basis because it provides valuable insights into the health and function of their autonomic nervous system (ANS) function and overall health during pregnancy.
As stated above, the ANS controls and regulates every vital function in the body, including heart rate, respiratory rate, digestion, and more. With “fight or flight” and “rest and relax” being the two main branches of the ANS, it’s important to track how it is functioning and whether things are out of balance or not.
HRV is a measure of the variation in time between consecutive heartbeats. A higher HRV indicates a more flexible and adaptable nervous system, which is associated with better overall health and resilience to stress during pregnancy. This also means reduced maternal stress, better sleep quality, improved cardiovascular health, and enhanced immune function. Additionally, maintaining a balanced ANS is essential for supporting proper blood flow to the placenta and optimal fetal development.
On the other hand, a lower HRV suggests an imbalanced or stressed ANS, which can lead to various health issues, commonly leading to a high-risk pregnancy.
Therefore any professionals working with pregnant women need to be using HRV technology as the foundation of their care protocols and programs, allowing them to not only establish a baseline at the onset of care but also to track and monitor progress via actual neurological change and improvement.
Measuring and tracking true Autonomic Nervous System and Vagus Nerve functions are, therefore, the foundation of our work as Prenatal PX Doctors. Each and every pregnant woman who walks into our offices first get an HRV test to measure their overall adaptability and parasympathetic or vagal nerve tone.
Below is an image with a series of three (3) HRV Scans performed on a pregnant woman throughout her pregnancy. The first scan on the far left shows the small white box way in the lower left quadrant of the HRV plot, indicating her parasympathetic nervous system and vagus nerve are both suppressed and shut down, allowing her sympathetic fight or flight system to run out of control.
Then as care progresses over the second and third trimester, you can see the white box move towards the center line and higher up towards the green circle, indicating that her subluxation and dysautonomia were vastly improved and her nervous system is now much calmer, balanced, and better regulated, which shows that she is more adaptable to the stressors of pregnancy and ready to conquer her birth!
