Comparison of basic characteristics
Among the 101 patients, 34 exhibited AHREs during the initial one year
after CIED implantation and were subsequently allocated to the AHRE
group, while the remaining 67 patients were allocated to the non-AHRE
group. Table 1 summarizes the basic clinical characteristics of the
included patients before CIED implantation. Statistical differences were
analyzed between the AHRE and non-AHRE groups. Although the
subpopulation of SSS patients was larger in the AHRE group than in the
non-AHRE group (p =0.05), the other parameters did not present any
statistical differences.
