Table 2. Incidence of study endpoints according to the ventricular conduction patterns.
| Study endpoint | Narrow QRS (n=4,136) | RBBB (n=363) | LBBB (n=280) | NICD (n=378) | p value | |
|---|---|---|---|---|---|---|
| Primary endpoint | 1,549 (37.5) | 161 (44.4) | 147 (52.5) | 188 (49.7) | <0.001 | |
| All cause death | 705 (17.0) | 77 (21.2) | 61 (21.8) | 96 (25.4) | <0.001 | |
| Rehospitalization | 1,066 (25.8) | 117 (32.2) | 111 (39.6) | 127 (33.6) | <0.001 | |
Values are expressed as number (%).
LBBB = left bundle branch block; NICD = nonspecific intraventricular conduction delay; RBBB = right bundle branch block.
