Are 2-dimensional guided M-mode echocardiography measurements reproducible with low intra-observer variability?
This study demonstrates that 2-dimensional guided M-mode echocardiography has good intra-observer reproducibility and low variability in a Nigerian clinical setting.
Supports reproducibility of 2D-guided M-mode echo in this setting; leaves open generalizability and requires prospective validation.
BACKGROUND: Although echocardiography is a useful and cost-effective technique for the detection of morphological and functional cardiac abnormalities, it has a main limitation in its subjectivity. Therefore the aim of the present study was to assess the intra-observer reproducibility and validity of 2-dimensional guided M-mode echo measurements at a Nigerian metropolitan Hospital. METHODS: Standard echocardiographic examination was performed on twenty randomly selected patients (11 men and 9 women) aged 59.8 +/- 12.6 years in two different sessions seven days apart. RESULTS: A good degree of intraobserver agreement was observed between test 1 and test 2. The correlation coefficient between the first and second studies ranged between 0.60 and 0.96; measurement errors between 0.050 and 0.205. CONCLUSION: We would conclude that 2-dimensional guided M-mode measurements at echocardiography performed at our centre are reproducible with low intra-observer variability.
