The Tei index for evaluation of fetal myocardial performance in sick fetuses

Early Human Development, 2005
OBJECTIVE: The Tei index is a useful, new, noninvasive Doppler index of combined systolic and diastolic function calculated by isovolumic relaxation time plus isovolumic contraction time divided by ejection time.

Utility of right ventricular Tei index in the noninvasive evaluation of chronic thromboembolic pulmonary hypertension before and after pulmonary thromboendarterectomy. [PDF]

JACC: Cardiovascular Imaging, 2009
ObjectivesWe evaluated the utility of tissue Doppler-derived right ventricular (RV) Tei (or myocardial performance) index in patients with chronic thromboembolic pulmonary hypertension (CTEPH) before and after pulmonary thromboendarterectomy (PTE) and ...

Effects of valve dysfunction on Doppler Tei index

Journal of the American Society of Echocardiography, 2002
Recently proposed Doppler Tei index, defined as the sum of isovolumic contraction time or mitral valve closure to aortic valve opening time and isovolumic relaxation time or aortic valve closure to mitral valve opening time divided by ejection time, is a simple measure which enables noninvasive estimation of combined systolic and diastolic function and

Age dependency of the Tei index of myocardial performance

Journal of the American Society of Echocardiography, 2004
Despite its clinical use as a sensitive measure of left ventricular performance, little is known about whether the Tei index is influenced by aging. We determined the Tei index in 141 subjects without cardiovascular disease (age 16-78 years). There were statistically significant variations in ejection time, isovolumic relaxation time, and the Tei index

The Tei index: A new prognostic index for patients with symptomatic heart failure

Journal of the American Society of Echocardiography, 2002
The Tei index (TI) is a new echocardiographic/Doppler index of combined systolic and diastolic function, calculated as isovolumic relaxation time plus isovolumic contraction time divided by ejection time. This purpose of this study was to explore the prognostic value of TI in patients with heart failure from left ventricular (LV) systolic dysfunction ...

The Tei Index and Asymptomatic Myocarditis in Children With Severe Dengue

Pediatric Cardiology, 2013
This study aimed to assess myocardial involvement in infants and children with severe dengue (as per the new World Health Organization [WHO] classification 2009) using the Tei index. This prospective observational study was conducted in the Department of Pediatrics, PGIMER and the associated Dr. RML Hospital, New Delhi from August to December 2010. The

An Echocardiographic Study of the Limitations of the Tei Index in Aortic Stenosis

Echocardiography, 2009
Background: The omnibus Tei index, the sum of isovolumic contraction and relaxation times divided by the ejection time, is a good indicator of global cardiac function. However, these time intervals can be influenced by valvular heart disease and the role of the Tei index among patients with aortic stenosis (AS) and left ventricular systolic ...

The Tei index and exercise capacity.

The Journal of sports medicine and physical fitness, 2001
Cardiac function time intervals are known to change with aerobic fitness. Recently, the Tei index of cardiac function [defined as the sum of the isovolumetric contraction (ICI) and isovolumetric relaxation intervals (IRI) divided by the left ventricular ejection time (LVET)] has been proposed to be a very sensitive determinant of cardiac function in ...

TEI Index in elite sprinters and endurance athletes.

The Journal of sports medicine and physical fitness, 2015
Aerobic training has been reported to have a positive effect on myocardial performance index. The aim of the present study was to examine the myocardial performance index (MPI) in sprinters and endurance athletes.A total of 66 elite male athletes (36 sprinter and 30 endurance athletes) and 33 agematched sedentary controls voluntarily participated in ...
