Quantification of regional left ventricular wall motion in newborns by color kinesis.
BACKGROUND Normal values for regional left ventricular wall motion, although documented in adults, have not been reported in healthy newborns. METHODS This study prospectively evaluated global and segmental systolic and diastolic cardiac function by color kinesis in clinically asymptomatic healthy newborns. RESULTS Eighty-eight asymptomatic infants who were less than 48 hours old were studi...
متن کاملObjective evaluation of regional left ventricular wall motion during dobutamine stress echocardiographic studies using segmental analysis of color kinesis images.
OBJECTIVES To test the feasibility of objective and automated evaluation of echocardiographic stress tests, we studied the ability of segmental analysis of color kinesis (CK) images to detect dobutamine-induced wall motion abnormalities and compared this technique with inexperienced reviewers of conventional gray-scale images. BACKGROUND Conventional interpretation of stress echocardiographic...
متن کاملRegional wall motion abnormalities during early diastole in patients with hypertensive left ventricular hypertrophy: a Doppler tissue echocardiographic study.
To investigate left ventricular wall motion asynchrony in patients with hypertensive heart disease, we measured regional myocardial velocity in hypertensive patients with left ventricular hypertrophy and in normotensive individuals using tissue Doppler imaging. The endocardial velocity and the myocardial velocity gradient were measured in the basal and mid segments of the septal and posterior w...
متن کاملEchocardiographic wall motion abnormalities in hypertensive patients with electrocardiographic left ventricular hypertrophy: the LIFE Study.
There is limited information on correlates of left ventricular wall motion (WM) abnormalities in ambulatory patients with hypertension and ECG left ventricular hypertrophy by Cornell voltage-duration product and/or Sokolow-Lyon voltage criteria. Therefore, we assessed the prevalence and the correlates of echocardiographic global and segmental left ventricular WM abnormalities in 942 hypertensiv...
متن کاملValidity of echocardiographic determination of left ventricular systolic wall thickening.
Previous direct measurements of left ventricular systolic wall thickening (SWT) in animal studies have yielded values approximately one-half those found echocardiographically in humans, suggesting a possible overestimation of SWT by echocardiographic techniques. To test the validity of echocardiographic SWT measurements, the relationship between echocardiographically determined end-diastolic an...
