Study protocol with examples of the tracings taken from the same study participant before (A) and after (B) parasympathetic cardioneuroablation (PCNA). An asterisk (*) indicates the familiarization period, while the arrow points to a high-dose atropine bolus. Note that, PCNA leads to the suppression of beat-to-beat cardiac parasympathetic activity while blood pressure variability remains unchanged.
