Changes in time and geometrical domain parameters of heart rate variability during a 12 − month follow − up.A sharp decrease in medium HRV geometrical and time domain parameter values were notable in 13 sheep immediately after the RFA in the left atrium. HRV TI (a) remained decreased for 6 months and RMSSD (b) for 3 months before returning to preprocedural values. SDNN (c) remained decreased for a whole study period, though with a tendency to increase towards the end of the 12 months follow – up
