cSNRT—corrected sinus node recovery time. PM—pacemaker; AVB—atrioventricular block; SNRT—sinus node recovery time, HV—His-ventricle interval. Remarks: 1 last CNA—first CNA in patients with one procedure or second CNA in patients with redo-CAN; 2 Two patients had delayed TLE due to extensive redo-CNA and invasive control with ECVS.
