Randomized Controlled Trial Multicenter Study Comparative Study Clinical TrialInterstudy reproducibility of parameters of left ventricular diastolic function: a Doppler echocardiography study.
Interstudy reproducibility of echocardiography for the assessment of parameters of left ventricular (LV) diastolic function is disputed. Therefore, we evaluated the reproducibility of echocardiography for assessment of LV diastolic Doppler parameters in 40 consecutive patients (age range: 19-77 years), who underwent 2 echocardiographic examinations by trained sonographers following a standard protocol, in conditions in which intrapatient sources of variability were minimized. ⋯ Under a standardized echocardiographic protocol and sonographers' training program, echocardiography can be a reproducible method for serial assessment of Doppler parameters of LV diastolic function, especially in cohort studies.
