Why the study?
Are measurements of systolic myocardial velocities and displacement using mean spectral Tissue Doppler frequencies concordant with colour Tissue Doppler and M-mode in healthy individuals?
Are measurements of systolic myocardial velocities and displacement using mean spectral Tissue Doppler frequencies concordant with colour Tissue Doppler and M-mode in healthy individuals?
Left ventricular systolic myocardial measurements based on mean spectral Tissue Doppler frequencies are highly concordant with colour TD and M-mode, supporting their interchangeable use in clinical practice.
No takes yet. Share an insight, caveat, or question.
May support interchangeable spectral and colour TD use in research; leaves open validation in clinical populations.
Manouras et al. (2009) studied this question.
