Clinical Context: HRV is a wellness and autonomic metric; clinical cardiology evaluations are needed if cardiac arrhythmias are suspected.
Diagnostic Consideration: A higher HRV indicates healthy parasympathetic vagal modulation, whereas a depressed HRV indicates sympathetic dominance and low physiological resilience.
Enhancing vagal nerve signaling through upper cervical alignment directly supports improved parasympathetic tone, lifting baseline HRV scores.
The cranio-cervical junction (where the skull meets the Atlas and Axis vertebrae) is the primary structural crossroads of the central nervous system. When misalignment occurs here, it can create mechanical traction on the brainstem, impede venous drainage, and disturb autonomic balance. Hope Southlake uses calculated 3D digital imaging to gently reposition these vertebrae without any twisting, popping, or cracking.
You used to enjoy working out, but now even light walking or basic household chores causes your heart to spike, leaves you dizzy, and triggers a multi-day physical crash.
