2. -Doppler Ultrasound Doppler ultrasound is a noninvasive test that can be used to measure your blood flow and blood pressure by bouncing high-frequency sound waves off circulating red blood cells. A regular ultrasound uses sound waves to produce images, but can't show blood flow. A water-soluble gel is placed on a handheld device called a transducer, which directs the high-frequency sound waves to the artery or veins being tested.
3. Uses Poorly functioning valves in your leg veins, which can cause blood or other fluids to pool in your legs Narrowing of an artery, such as those in your neck Decreased blood circulation into your legs Sound waves during pregnancy monitor how fast blood is moving in the umbilical blood flow
4. -Echocardiography aka ECHO A noninvasive diagnostic method using ultrasound to visualize internal cardiac structures. The test gives your doctor information about the size and shape of your heart and how well your heart's chambers and valves are working. Echo also can be done to detect heart problems in infants and children. The test also can identify areas of heart muscle that aren't contracting normally due to poor blood flow or injury from a previous heart attack. Echo can detect possible blood clots inside the heart, fluid buildup in the pericardium, and problems with the aorta.
5. -Stress Testing A stress test helps determine how well a person’s heart works. The patient is hooked up to a machine that monitors the heart rate, breathing, blood pressure, electrocardiogram, and oxygen. The patient is usually on a treadmill which is why this test is sometimes called treadmill test. An order for a stress test may be to: Diagnose coronary artery disease Diagnose a possible heart-related cause of symptoms such as chest pain, shortness of breath or lightheadedness Determine a safe level of exercise Check the effectiveness of procedures done to improve coronary artery circulation in patients with coronary artery disease or Predict risk of dangerous heart-related conditions such as a heart attack. If any abnormalities are detected, the patient is advised to stop or slow down the rate at which they are going.
