A Noninvasive Method for Characterizing Ventricular Diastolic Filling Dynamics
We developed a novel method for estimating a single parameter (τD) which summarizes the diastolic filling dynamics of the ventricle that governs the effects of diastolic filling time on stroke volume. The method involves the analysis of beat-to-beat fluctuations in heart rate, arterial blood pressure, and left ventricular stroke volume, each of which may be measured noninvasively in humans. In ...
متن کاملEarly diastolic filling dynamics in diastolic dysfunction
BACKGROUND The aim of the study was to determine the relationship between the rate of peak early mitral inflow velocity and the peak early diastolic mitral annular tissue velocities in normal controls and to compare them with subjects with diastolic dysfunction. METHODS The relationship between early passive diastolic transmitral flow and peak early mitral annular velocity in the normal and i...
متن کاملRight ventricular diastolic filling in the first day of life.
To evaluate the effects of altered preload on the Doppler flow pattern of right ventricular inflow in the first day of life, serial Doppler echocardiography of the pulmonary artery (PA) and tricuspid valve was performed in 16 normal neonates at 2, 12, and 24 hr. A computer-interfaced digitizer pad was utilized to measure the followings: PA flow velocity-time integral, total transtricuspid flow ...
متن کاملEffects of verapamil on left ventricular systolic function and diastolic filling in patients with hypertrophic cardiomyopathy.
Verapamil improves exercise capacity in patients with hypertrophic cardiomyopathy (HCM), but its mechanism of action are unknown. We examined the effects of oral verapamil (320-480 mg/day) on resting left ventricular (LV) systolic and diastolic function in patients with HCM. High-temporal-resolution time-activity curves from gated technetium-99m radionuclide angiograms were analyzed before and ...
متن کاملImpairment of diastolic function by shortened filling period in severe left ventricular disease.
A dilated left ventricle with reduced ejection fraction is usually attributed to impaired systolic function. To investigate the possibility that ventricular filling might also be disturbed, M mode echocardiograms, phonocardiograms, and Doppler cardiograms were recorded in 30 patients with ventricular disease of varying cause. All but four had functional mitral regurgitation. The size of the lef...
