Evaluation of left ventricular function by echocardiography.
Ventricular minor-axis dimensions were measured by echocardiography at end-systole (Ss) and end-diastole (SD)) in five groups of patients: (I) normal; (II) mitral stenosis; (III) compensated volume overload; (IV) idiopathic hypertrophic subaortic stenosis; and (V) congestive heart failure. Cardiac pump function was evaluated by determination of left ventricular volumes and ejection fraction (EF...
متن کاملEvaluation of Left Ventricular Diastolic Function by Echocardiography
The normal cardiac cycle consists of two phases, systole and diastole, which are repeated over time to maintain an adequate cardiac output. The systole has been traditionally regarded as the main capital phase, leaving at diastole as a secondary process and almost forgotten. However, today we know that diastole is a crucial stage in the functioning of the heart. Its dysfunction can lead even in...
متن کاملEvaluation of Right Ventricular Function by Tissue Doppler Echocardiography in Asthmatic Children
BackgroundAsthma is the most chronic inflammatory disorder of the airways in children and asthmatic patients can experience cardiac dysfunction, pulmonary hypertension and finally cor pulmonale later in life. We aimed to investigate Right Ventricular (RV) functions in asthmatic children by conventional and tissue Doppler echocardiography (TDE).Materials and Methods Pulmonary function tests, con...
متن کاملAssessment of left ventricular function by three-dimensional echocardiography
Accurate determination of LV volume, ejection fraction and segmental wall motion abnormalities is important for clinical decision-making and follow-up assessment. Currently, echocardiography is the most common used method to obtain this information. Three-dimensional echocardiography has shown to be an accurate and reproducible method for LV quantitation, mainly by avoiding the use of geometric...
متن کاملLeft ventricular structure and function by echocardiography in childhood swimmers.
The purpose of this study was to determine the differences in the left ventricular dimensions, mass index and function in school-aged swimmers by echocardiography. The study group consisted of 82 swimmers who participated in a systematic swimming training for at least six months, and the control group consisted of 41 sedentary children of similar age, sex and weight. In the study group, left ve...
