Table 3 Variabilities of Myocardial Strain and Strain Rate Measurement by 2-Dimensional Strain

From: Value of segmental myocardial strain by 2-dimensional strain echocardiography for assessment of scar area induced in a rat model of myocardial infarction

  Radial strain Circumferential strain Radial strain rate Circumferential strain rate
Intraobserver 5.8% 7.6% 6.3% 8.5%
Interobserver 6.1% 6.9% 8.0% 11%
