Performing exercise Doppler echocardiography may be useful to clarify symptoms of dyspnea or the etiology of acute pulmonary edema in patients with LV dysfunction. Ischemic mitral regurgitation is ...

Background Although the prognostic implications of severe mitral regurgitation (MR) are well recognised, they are less clear in moderate MR. We therefore explored the prognostic impact of both ...

The study investigates the prognostic impact of sex and sex‐related differences in patients hospitalized with heart failure with mildly reduced ejection fraction (HFmrEF). More data regarding the ...

The term dilated cardiomyopathy (DCM) refers to a spectrum of heterogeneous myocardial disorders that are characterized by ventricular dilation and depressed myocardial performance in the absence of ...

For Doppler ultrasound, Vmax and Vmean are the maximum and mean velocities in the sample volume, respectively. Whereas MRI is relatively expensive and most suited to imaging central vessels, Doppler ...

two approaches of computing velocity can be used to check the consistency of Doppler shifts and pseudoranges measurements. An efficient spoofing detection method based on the consistency check of ...

Figure 1. Doppler velocity palette. Inbound velocities (towards the radar) are shaded blue, with pale shades for light winds and dark shades for strong winds. Outbound velocities (away from the radar) ...

The Doppler circuitry determines the change in frequency and, this may only be translated into a blood velocity if the insonation angle is recorded and is included in the calculation. Nevertheless, ...

Abstract: Time delay and Doppler shift between the echo signal and the reference signal are two most commonly used measurements in target localization for the passive radar. Doppler rate, which can be ...
