Absolute Medical offers aselection of echocardiography ultrasound machines from industry leading manufacturers including Acuson, Biosound, GE and Philips. These ultrasound machines assess the size, structure and movement of the heartís 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.
