Table 2 The percentage of patients with more than 20 ms differences between AVopt-AV and AVopt-V

From: An electrographic AV optimization for the maximum integrative atrioventricular and ventricular resynchronization in CRT

 

Patients with directly measured AV

(n = 35)

Patients with calculated AV*

(n = 49)

SAV

22 (62.9%)

22 (44.9%)

PAV

20 (57.1%)

29 (59.2%)

SAV and PAV

17 (48.6%)

17 (34.7%)

  1. *The Sensing/Pacing AVopt-AV and AVopt-V were calculated according to the following formulae:
  2. SAVopt-AV = 0.80 × Pend-As + 50 ms
  3. SAVopt-V = 0.60 × As-Vs + 15 ms
  4. PAVopt-AV = 0.70 × Pend-Ap + 70 ms
  5. PAVopt-V = 0.60 × Ap-Vs + 40 ms
