Figure 4 Ventricular pacing rate (VPR) of patient subgroups depicted on a logarithmic timeline. A: VPR of patients with high-degree atrioventricular block (AVB) after discharge. B: VPR of patients with high-degree AVB before transcatheter aortic valve implantation. C: VPR of patients with periprocedural/postprocedural high-degree AVB. Pat. = patient.
