Functional Characteristics of the Left Ventricular Inflow and Outflow Tracts.
• The heart chambers contract sequentially and any significant alteration in spread of the electrical activity may bring about a change in sequence. While recording contractile force from multiple sites on a single ventricle, it was noted that different portions of the ventricular myocardium showed consecutive onset of systole. Puff employed high-speed cinematography to study changes in ventric...
متن کاملDevelopment and Morphology of the Ventricular Outflow Tracts
It is customary, at the current time, to consider many, if not most, of the lesions involving the ventricular outflow tract in terms of conotruncal malformations. This reflects the introduction, in the early 1940s, of the terms conus and truncus to describe the components of the developing outflow tract. The definitive outflow tracts in the postnatal heart, however, possess three, rather than t...
متن کاملthe effect of functional/notional approach on the proficiency level of efl learners and its evaluation through functional test
in fact, this study focused on the following questions: 1. is there any difference between the effect of functional/notional approach and the structural approaches to language teaching on the proficiency test of efl learners? 2. can a rather innovative language test referred to as "functional test" ge devised so so to measure the proficiency test of efl learners, and thus be as much reliable an...
15 صفحه اولMechanisms of diastolic intraventricular regional pressure differences and flow in the inflow and outflow tracts.
OBJECTIVES We sought to investigate the mechanisms of left ventricular (LV) intracavitary early diastolic flow during changes in contractility and loading. BACKGROUND There is limited understanding of how intracavitary flow velocities relate to intraventricular driving pressures. METHODS In 12 anesthetized dogs, we measured pressures in the left atrium (LA), LV at the mitral tip, apex, and ...
متن کاملLeft Ventricular Early Inflow–Outflow Index: A Novel Echocardiographic Indicator of Mitral Regurgitation Severity
BACKGROUND No gold standard currently exists for quantification of mitral regurgitation (MR) severity. Classification by echocardiography is based on integrative criteria using color and spectral Doppler and anatomic measurements. We hypothesized that a simple Doppler left ventricular early inflow-outflow index (LVEIO), based on flow velocity into the left ventricle (LV) in diastole and ejected...
