a, HR tachogram before, during and after VNS. Duration of nerve stimulation is indicated by the yellow line. Basal mean HR and mean HR during VNS are indicated by gray lines. The timepoints, for the representative ECG traces shown in b and c, are marked by blue circles. b,c, Surface ECG lead II and intracardiac leads HRAd, HRAp, RVd, and RVp are displayed during basal conditions (b) and during VNS (c). VNS stimulation artifacts are indicated (yellow). Representative recordings are obtained from a 4-month-old male mouse.
