Why the study?
Does color tissue Doppler accurately measure myocardial velocity compared to spectral tissue Doppler in patients with sinus rhythm?
Does color tissue Doppler accurately measure myocardial velocity compared to spectral tissue Doppler in patients with sinus rhythm?
Color tissue Doppler consistently underestimates myocardial velocity and overestimates E/Ea compared to spectral tissue Doppler, indicating poor reliability between the two methods.

CTD should not substitute for STD in diastolic assessment; leaves open validation of modality-specific cutoffs against outcomes.
