Table 2 PR interval duration dynamics and average No of syncope in patient history in relation to the VASIS type
From: PR interval as a predictor of syncope in tilt-up testing in adolescents and young adults
VASIS I | VASIS III | p | |
|---|---|---|---|
Initial PR interval (ms) | 142.8 ± 2.3 | 150.6 ± 3.2 | 0.049 |
PR before syncope (ms) | 102.9 ± 2.3 | 114.1 ± 2.8 | 0.003 |
PR interval change ratio (%) | 27.6 ± 1.3 | 23.8 ± 1.5 | 0.047 |
PR after syncope (ms) | 133.8 ± 2.1 | 138.7 ± 2.3 | 0.093 |
No of previous syncope | 3.0 ± 0.3 | 5.7 ± 1.0 | 0.006 |
