What test are used to diagnose heart disease

ECG:
    Electrocardiography is the process of recording
the electrical activity of the heart over a period of time using electrodes placed on the skin.
These electrodes detect the tiny electrical changes on the skin that arise from the heart muscle's
electrophysiologic  pattern of depolarizing and repolarizing during each heartbeat.
It is a very commonly performed cardiology test.

ECHO:
    An echocardiogram, often referred to as a cardiac echo or simply an echo,
is a sonogram of the heart.Echocardiography uses standard two-dimensional, three-dimensional,
and Doppler ultrasound to create images of the heart.

Exercise Treadmill Test

    An Exercise Stress Test is used as a means of assessing how your heart and blood vessels
respond to physical exertion. An ECG is recorded at rest whilst walking on a treadmill.
Throughout the test a Cardiac Technician and a Medical Practitioner will supervise you and look
for indications that your heart is not getting enough oxygen, signalling obstructed coronary arteries.
