This variation is called the Doppler spectrum. If you are a Mayo Clinic patient, this could While E and e wave velocities decreased progressively with age, there was an increase in A wave, in E wave deceleration time, and in E/e ratios. During this test, the ultrasound images will be produced while you exercise on a treadmill, ride a stationary bike, or receive medication to make your heart beat faster. Continuous variables were expressed as mean + SD and according to tertiles. Your provider may want you to have more imaging tests, such as cerebral, CT or magnetic resonance angiography. Results. The ankle brachial index, or ABI, is a simple test that compares the blood pressure in the upper and lower limbs. Doppler ultrasound can be used to determine the velocity (the speed in a given direction) of blood. Both genders were well represented with a slight predominance of women. During a Doppler ultrasound, a handheld device emits sound waves that bounce off moving objects, such as blood cells. E wave velocity and E/A ratio were lower in older patients (60 years) in both genders, and there was a negative significant correlation between these parameters and age (r = 0.31, P 0.001 and r = 0.61, P 0.001; respectively) in men. There were no significant differences in s, e, and a wave velocities between male and female. Thanks to all authors for creating a page that has been read 257,629 times.
