Evaluation of minimum, maximum, and mean HR, as well as HRV, pre-procedure, at 6 months and at 12 months. (A) Minimum HR, (B) Median HR, (C) Maximum HR, (D) SDNN (SD of NN intervals), (E) PNN50% (percentage of successive RR intervals that differ by > 50 ms), (F) RMSSD (root mean square of successive RR interval differences), (G) VLF (absolute power of the very-low-frequency band (0.0033–0.04 Hz)), (H) LF (absolute power of the low-frequency band (0.04–0.15 Hz)), (I) HF (absolute power of the high-frequency band (0.15–0.4 Hz)). CNA cardioneuroablation, HR heart rate.
