Investigating myocardial performance in normal and sick fetuses by abdominal Doppler signal derived indices

Current Research in Physiology, 2021
Introduction: Fetal myocardial performance indices are applied to assess aspects of systolic and diastolic function in developing fetal heart. The aim of this study was to determine normal values of Tei Index (TI) and modified TI (KI) for systolic and ...

Effect of septoplasty on left ventricular myocardial performance in patients with nasal septum deviation

Brazilian Journal of Otorhinolaryngology, 2022
Introduction: Nasal septum deviation is the leading cause of upper airway obstruction. Chronic upper airway obstruction may cause myocardial injury due to chronic hypoxia. Effects of septoplasty on left venticular diastolic and sistolic functions are not

Types of Diastolic Dysfunction of the Left Ventricle in Adolescents with Myocardial Pathology

Zdorovʹe Rebenka, 2014
In adolescents with myocardial pathology during isometric tests we detected three types of diastolic dysfunction of the left ventricle (LV) of the heart, depending on E/A ratio.

Systolic‐dominant coronary flow in rats and mice: Challenging the diastolic paradigm across conscious and anaesthetized states

Experimental Physiology, EarlyView.
Abstract Extensive research in humans, dogs, rabbits, rats, mice and other mammals has consistently demonstrated that coronary blood flow (CBF) peaks during ventricular diastole. For example, studies using transthoracic Doppler echocardiography in anaesthetized rats and mice, isolated blood‐perfused rat hearts and Doppler probes sutured to the ...
