ECG:
|
| |
This measures the
electrical activity of the heart. A change in
the ECG pattern can be indicative of the presence
of heart disease. |
| |
The doctor usually
looks for two types of changes –those which
indicate a block in the coronary arteries and
changes which indicate a problem with the rhythm
of the heart beats, such as palpitations |

Stress test
/ stress ECG: |
| |
The stress ECG provides
more information than a rest ECG since the oxygen
demand on your heart is greater while exercising. |
| |
A positive stress
test indicates that there are changes on your
ECG which are suggestive of a block in your heart
(coronary) arteries. A stress test also gives
you information on your cardiovascular fitness. |

Thallium
stress test / nuclear medicine stress test: |
| |
This stress test is
like a regular stress test, but a dye is injected
into the heart and pictures are taken of the heart,
before and after the stress test. |
| |
This can detect areas
of the heart muscle that have been damaged by
a heart attack and areas that are not getting
enough oxygen due to partial blockages of the
coronary arteries. Nuclear medicine tests can
also provide information on the functioning of
the left ventricle. |
