Comparison of the prevalent morphology of ventricular arrhythmias between athletes with 1–50 PVBs and athletes with >50 PVBs
| Morphology | Athletes with 1–50 PVBs | Athletes with >50 PVBs | |
|---|---|---|---|
| n = 250 | n = 36 | ||
| Infundibular | 70 (29%) | 16 (44%) | P = 0.04* |
| Fascicular (RBBB/QRS ≤ 130 ms) | 69 (28%) | 8 (22%) | P = 0.6 |
| LBBB/superior axis | 23 (8%) | 1 (3%) | P = 0.1 |
| RBBB/QRS > 130 | 50 (20%) | 5 (14%) | P = 0.2 |
| Polymorphic | 38 (15%) | 6 (17%) | P = 0.8 |
Data are given as number (percentage).
LBBB, left bundle branch block; PVBs, premature ventricular beats; RBBB, right bundle branch block.
