COMPARATIVE THICKENING FRACTION OF SEPTUM AND POST-ERIOR LEFT VENTRICULAR WALL IN NORMAL CHILDREN ON ECHOGRAM
Although the ventricular septum (S) participates in left ventricular (LV) contraction (LVC) in normal subjects, no data are available regarding the relative contribution of S as compared to the LV posterior wa...

EVALUATION OF LEFT VENTRICULAR PREEJECTION SYSTOLE IN NORMAL CHILDREN BY ECHOCARDIOGRAPHY
The period of systole prior to left ventricular (LV) ejection (PES) can be assessed from echograms (E), by measuring the interval from the onset of the electrical Q wave to: coaptation of the mitral valve (Q-M...

THE RATIO OF SYSTOLIC TIME INTERVALS OF LEFT VENTRICLE IN NORMAL CHILDREN-ECHOCARDIOGRAPHIC STUDY
Current techniques utilize data derived from the aortic valve (AV) to determine the ratio between the pre-ejection (PEP) and ejection period (EP) of left ventricle (LV) in children. Mitral valve (MV), septum (...

ECHOCARDIOGRAPHIC MEASUREMENT OF RIGHT VENTRICULAR OUTFLOW TRACT IN NORMAL CHILDREN
In order to enchance the echocardiographic assessment of the size and function of the right ventricle (RV), we evaluated the measurement of the right ventricular outflow tract (RVOT) on echogram, and compared ...

ANALYSIS OF THE TEMPORAL SEQUENCE OF LEFT VENTRICULAR SYSTOLE IN NORMAL CHILDREN BY ECHOCARDIOGRAPHY
Little data are available regarding measurements of the active state of left ventricular (LV) segmental contraction. Thus we performed echograms (E) in 40 normal school children, to establish and relate normal...

RELATIONSHIP BETWEEN LEFT VENTRICULAR AND LEFT ATRIAL ECHOCARDIOGRAPHIC DIAMETERS IN NORMAL CHILDREN
Since the entire stroke volume traverses each cardiac chamber in normal subjects, a study was undertaken to investigate the relationship of left atrial (LA) to left ventricular (LV) size. Thus, echocardiograms...

BLOOD PRESSURE RANGE IN NORMAL CHILDREN: MATURATIONAL DIFFERENCES BETWEEN MALES AND FEMALES
Limited recent data are available on the range of blood pressure (BP) in normal children at different ages. Thus we studied 239 normal school children from 5 to 14 years (Y) of age: 136 boys and 103 girls. BP ...

CARDIAC MUSCLE PERFORMANCE IN LAMBS: DISPARITY BETWEEN CONTRACTILE ELEMENT VELOCITY OF LEFT AND RIGHT VENTRICLES
We assessed muscle performance of the newborn heart by examining left (LV) and right (RV) ventricular myocardial mechanics in 18 open chested lambs (ages 1-40 days) anesthetized with alpha chloralose and instr...
