LIGHTOWLER, C. et al. Determination of the normal value of the left ventricular Tei index in healthy dogs. InVet [online]. 2006, vol.8, n.1, pp.41-49. ISSN 1668-3498.

Recent studies have showed that in the majority of the patients with congestive cardiac failure coexist alteration of systolic and diastolic function and in many cases the systolic function is normal and the cardiac failure this supported only by the diastolic dysfunction. This fact has therapeutic, diagnostic and prognostic implications. Recently, Tei and co-workers proposed a new Doppler index that permits the combined evaluation of some of the systolic and diastolic intervals. Supported by these antecedents the authors determined the normal value of the left ventricular Tei index in healthy dogs in order to evaluate the systodiatolic function. A mean value of 0,372 with a standard deviation of 0,04 was obtained. Likewise the authors could verified that not correlation exists with cardiac rate (P> 0,0975) neither with the systolic arterial pressure (P> 0,0895) but a significant correlation exists with the left ventricular fractional shortening (P<0,05).
