Table 5. Predictors of Persistent RV Pacing After PPM Implantation.
| RV pacing-dependent (n = 8) | Non-RV pacing-dependent (n = 17) | Odds ratio (95% CI) | P-value | |
|---|---|---|---|---|
| RBBB | 8/8 | 2/17 | 105.4 (4.52 - 2,458.5) | 0.004 |
| Bifascicular block | 5/8 | 2/17 | 12.50 (1.6 - 97.65) | 0.02 |
| QRS duration > 120 ms | 8/8 | 3/17 | 70.43 (3.23 - 1,535.22) | 0.007 |
| Intra-procedural complete heart block | 7/8 | 6/17 | 12.83 (1.26 - 130.52) | 0.03 |
| NCC volume > 239.2 mm3 | 6/8 | 0/16 | 85.80 (3.61 - 2,041.00) | 0.006 |
The P-values shown are derived from two-tailed Fisher’s exact test for categorical variables. Patients who were non-RV pacing-dependent at 30 days and patients who were RV pacing-dependent at 30 days patients were separately compared. RBBB: right bundle branch block; CI: confidence interval; NCC: non-coronary cusp; RV: right ventricular; PPM: permanent pacemaker.
