Key result
Heart rate variability analysis detected a high frequency component of normal amplitude in 6% of cardiac transplant recipients, serving as a marker for gradual parasympathetic reinnervation.

HRV may mark gradual reinnervation in transplant recipients; leaves open its prognostic value and clinical utility.

Can heart rate variability analysis detect functional cardiac allograft reinnervation in heart transplant recipients?
A small minority of heart transplant recipients demonstrate a normal high-frequency component of heart rate variability, suggesting that gradual parasympathetic reinnervation of the sinus node can occur over time.
Ramaekers et al. (1996) conducted an observational in Cardiac transplantation (n=124). Heart rate variability (HRV) analysis was evaluated on Presence of high frequency (HF) component of HRV as a marker for parasympathetic reinnervation. Heart rate variability analysis detected a high frequency component of normal amplitude in 6% of cardiac transplant recipients, serving as a marker for gradual parasympathetic reinnervation.
