Table 1 LV mass measured in 19 patients by three observers by manual tracing of two dimensional echocardiography (2DE) and semiautomated surface detection applied to real time three dimensional echocardiography (RT3DE).
| Observer | |||
|---|---|---|---|
| 1 | 2 | 3 | |
| RT3DE (g) | 119 (41) | 127 (37) | 129 (35) |
| 2DE (g) | 99 (37)* | 70 (21)* | 95 (26)* |
Data are mean (SD). All values were compared with a magnetic resonance reference of 126 (39) g.
*p<0.05, paired t test versus magnetic resonance.
