2. Cardiac Scan
• Patient is given radioactive thallium
intravenously and then scanning equipment
is used to visualize the heart. It is especially
useful in determining myocardial damage

3. Cardiac Scan
• During a cardiac CT scan, an x-ray machine will
move around your body in a circle. The machine
will take a picture of each part of your heart. A
computer will put the pictures together to make a
three-dimensional (3D) picture of the whole heart.

5. Echocardiography
• Noninvasive diagnostic method using
ultrasound to visualize internal cardiac
structures
• Cardiac valve activity can be evaluated
using this method

7. Echocardiography
• Echocardiography was an early medical application
of ultrasound. Echocardiography was also the first
application of intravenous contrast-enhanced
ultrasound. This technique injects gas-filled
microbubbles into the venous system to improve
tissue and blood delineation.

8. Purpose
• Echocardiography is used to diagnose
cardiovascular diseases. In fact, it is one of the
most widely used diagnostic tests for heart
disease. It can provide a wealth of helpful
information, including the size and shape of the
heart, its pumping capacity and the location and
extent of any damage to its tissues.

10. Holter monitor
• Portable ECG(electrocardiography)
monitor worn by a patient for a period of a
few hours to a few days to assure the heart
and pulse activity as the person goes
through the activities of daily living.
• Used to assess a patient who experiences
chest pain and unusual heart activity during
exercise and normal activities.

12. Holter monitor
• Electrodes (small conducting patches) are stuck
onto your chest and attached to a small recording
monitor. You carry the Holter monitor in a pocket
or small pouch worn around your neck or waist.
The monitor is battery operated.

13. Consideration
• While wearing the device, avoid:
• Electric blankets
• High-voltage areas
• Magnets
• Metal detectors
It is very important for you to keep a diary of
symptoms. The diary should include the date, time of
day, type, and duration of symptoms.
