The diagnostic procedure is a method or technique used to

identify or to see the nature of disease or disorder. It is also

used to figure out what kind of disease is present. This is

followed in making a medical diagnosis and this excludes

procedures which are primarily carried out on specimens in a

laboratory.

A Doppler ultrasound test uses reflected sound waves to evaluate

blood as it flows through a blood vessel.

An ultrasound of the heart allows the cardiologist to perfectly see

the whole tissues which constitute the heart as well as its kinetics.

It helps doctors evaluate blood flow through the major arteries and

veins of the arms, legs, and neck. It can show blocked or reduced

blood flow through narrowing in the major arteries of the neck that

could cause a stroke.

It’s a handheld instrument that is passed lightly over the skin above

a blood vessel. The transducer sends and receives sound waves that

are amplified through a microphone.

The sound waves bounce off solid objects, including blood cells. The

movement of blood cells causes a change in pitch of the reflected

sound waves which is called Doppler Effect.

An echocardiogram, often referred to in the medical community as

a cardiac ECHO or simply an ECHO, is a sonogram of the heart

An echocardiogram is a test that uses sound waves to create a

moving picture of the heart. The picture is much more detailed than

a plain x-ray image and involves no radiation exposure.

An instrument called a transducer that transmits high-frequency

sound waves is placed on your ribs near the breast bone and

directed toward the heart.

The echocardiography machine converts these impulses into

moving pictures of the heart. The Doppler probe records the motion

of the blood through the heart.

An echocardiogram allows doctors to see the heart beating, and to

see many of the structures of the heart.

A cardiac stress test is a medical test that indirectly reflects arterial

blood flow to the heart during physical exercise.

When compared to blood flow during rest, the test reflects

imbalances of blood flow to the heart's left ventricular muscle tissue

which is the part of the heart that performs the greatest amount of

work pumping blood.

A stress test, sometimes called a treadmill test or exercise test, helps

a doctor find out how well your heart handles work.

As your body works harder during the test, it requires more oxygen,

so the heart must pump more blood.

The test can show if the blood supply is reduced in the arteries that

supply the heart. It also helps doctors know the kind and level of

exercise appropriate for a patient.
