Stress tissue Doppler imaging (stress echo with tissue Doppler)

Stress tissue Doppler imaging (stress echo with tissue Doppler)


An important limitation with stress tissue Doppler imaging (stress echo with tissue Doppler) is the technical challenge of acquiring both two dimensional and tissue Doppler echocardiographic information during exercise. Peak myocardial systolic velocities (Sa) increase with both exercise and dobutamine stress. Tissue Doppler techniques can identify abnormal segments in a better way than two dimensional echo and has a better reproducibility than it. Peak velocities 5.5 cm/s or less can identify abnormal segments with a sensitivity of 96% and specificity of 81% [1].
