Absolute Medical offers a selection of echocardiography ultrasound machines from industry leading买彩票APP有哪些 manufacturers including Acuson, Biosound, GE and Philips. These ultrasound machines assess the size, structure and movement of the heart’s chambers and valves. They can pinpoint areas of weakened heart muscle contraction, determine blood flow rates and pressure, detect possible tumors and blood clots in the heart, expose fluid build up in the pericardium, reveal problems with the aorta, and catch possible heart and cardiovascular diseases. External transducers are used to perform transthoracic echocardiograms (TTE), stress echocardiograms, and doppler echocardiograms. Internal transducers are used during transesophageal echocardiograms (TEE). Echocardiography provides 3D images and, as high-frequency sound waves have not been shown to have any harmful effects, they may be performed safely on adults, children and infants.
