Heart rate variability in a patient after percutaneous renal denervation: a case report

Abstract

The overactivity of sympathetic component of autonomic nervous system is implicated in the genesis and progression of hypertension. We report the heart rate variability (HRV) of a patient after renal denervation for treatment of medically resistant hypertension. Catheter based renal denervation done for treatment of resistant hypertension reduces blood pressure by reducing the central sympathetic drive. In the present study we found a significant decrease in low frequency component of HRV in one month follow-up period after the procedure. We propose a simple, non-invasive 5-minute HRV could be a predictor of effective renal sympathetic denervation. [Int J Res Med Sci 2013; 1(4.000): 584-586

The autonomic balance of heart rhythm complexity after renal artery denervation: insight from entropy of entropy and average entropy analysis

“…In practice, the HRV analysis has been attempted to assess the effectiveness of percutaneous renal denervation (RDN), an effective and safe treatment to reduce blood pressure (BP) by disrupting renal sympathetic nerves for the autonomic balance [ 6 , 7 ]. Applying the short-term HRV after RDN or renal nerve stimulation seems to provide a way to assess the state of the autonomic nervous system [ 8 , 9 ]. However, the relative changes of HRV after RDN were not always consistent with BP reduction and were not predictive of response to RDN [ 10 – 12 ].…”
