Comparison between values in the two groups with abnormal long axis function
| Long axis abnormalities | True positive | False positive | p value |
|---|---|---|---|
| Total excursion (cm) | 0.9–0.65 (n = 40) | 0.64–0.9 (n = 12) | NS |
| Abnormal shortening after A2 (mm) | 1–3 (n = 25) | 1–2.8 (n = 5) | NS |
| Peak lengthening rate (cm/s) | 4.5–2.5 (n = 72) | 4.5–2.7 (n = 18) | NS |
| Delayed onset of lengthening (ms) | 80–120 (n = 60) | 80–125 (n = 20) | NS |
n, number of segments showing each abnormality.
