Diagnostic utility of standard ECG amplitude criteria (Davignon et al*) for the determination of LVH in children on the basis of the first ECG/echo data pair
| ECG criteria | No. | ↑ LV mass, z score >2 (Echo) | LVH (ECG) | Sensitivity | Specificity |
|---|---|---|---|---|---|
| RV6 (%) | 443 | 34 (7.7) | 88 (19.9) | 12/34 (35.3) | 333/409 (81.4) |
| SV1 (%) | 442 | 34 (7.7) | 22 (5.0) | 5/34 (14.7) | 391/408 (95.8) |
| RV6 + SV1 (%) | 442 | 34 (7.7) | 43 (9.7) | 5/34 (14.7) | 370/408 (90.7) |
| QV6 (%) | 444 | 34 (7.7) | 107 (24.1) | 9/34 (26.5) | 312/410 (76.1) |
| QIII (%) | 417 | 27 (6.5) | 39 (9.4) | 0/27 (0.0) | 351/390 (90.0) |
| (−)TV6 (%) | 416 | 27 (6.5) | 5 (1.2) | 1/27 (3.7) | 385/389 (99.0) |
| R/S V1 (%) | 411 | 25 (6.1) | 4 (1.0) | 0/25 (0.0) | 382/386 (99.0) |
Amplitude data available on 67% (444/663) of children with qualitative assessment (present or absent) of ECG LVH.
