Key result
Off-line analysis of colour tissue Doppler during dobutamine stress is feasible (>90% in most segments) and reproducible in 11 left ventricular segments, with basal segments being most reliable.
Why the study?
Is off-line tissue Doppler measurement of regional myocardial function during dobutamine stress echocardiography feasible and reproducible?
Observational (n=92)
Is off-line tissue Doppler measurement of regional myocardial function during dobutamine stress echocardiography feasible and reproducible?
Off-line tissue Doppler measurement during dobutamine stress echocardiography is feasible and reproducible, particularly for systolic velocities in basal segments.

Supports research protocols using off-line tissue Doppler in dobutamine stress; leaves open routine clinical adoption pending validation.
Fraser et al. (2003) conducted an observational in Dobutamine stress echocardiography (n=92). Off-line post-processing of colour tissue Doppler was evaluated on Reproducibility (coefficients of variation) and feasibility of off-line measurements of regional myocardial velocities. Off-line analysis of colour tissue Doppler during dobutamine stress is feasible (>90% in most segments) and reproducible in 11 left ventricular segments, with basal segments being most reliable.
