In recent years, epidemiologic investigations have been performed in hypertensive subjects in the presence or absence of end-stage renal disease (ESRD). Subjects with end-stage renal disease ...

send out a radio wave and time how long it takes to get back via an echo. However, in practice, there are a number of trade-offs to consider. For example, producing a long pulse has more energy ...

Methods Central and peripheral pulse wave velocity (PWV) was measured using Doppler ultrasound and calculated by the ‘foot to foot’ method before and after exercise. PWV was initially measured at rest ...

Pulse wave Doppler can be used in the left atrial appendage to determine the flow velocity. A velocity of < 0.4 m/s indicates a higher risk, in general, of thromboembolism. Cardiac CT can be used ...

This measurement allows the recording of the pulse pressure at two different sites ... particularly of the foot of the pressure wave, and therefore, the calculation of the time delay between ...
