The
Changi General Hospital Clinical Measurement Unit conducts
various tests to assess heart, lung, brain, nerve, muscle
and urinary functions. These tests which are available
on doctors' requests, are useful in the diagnosis of
disease conditions.
Tests
Relating to the Heart
We conduct cardiac investigations are important in the
diagnosis of heart conditions such as coronary heart
disease, cardiomyopathy (disease of the heart muscles),
valvular heart disease (disease of the heart valves),
arrhythmias (heart disease associated with abnormal
heart rhythms), hypertension etc.
The
tests include:
12 Lead Electrocardiography
24 Hour Ambulatory Blood
Pressure Monitoring
24 Hour Ambulatory Holter
Monitoring
Dobutamine Stress Echocardiography
Echocardiography
Pacemaker Checks
Signal Averaging Electrocardiography
Tilt Test
Exercise Stress Echocardiography
Treadmill Exercise Test
Transoesophageal Echocardiography
Transtelephonic Electrocardiography
Tests
Relating to the Lungs
Lung function tests are helpful in diagnosing conditions
such as asthma and chronic obstructive lung disease.
These tests are also useful in monitoring progress and
in assessing response to treatment. Lung function tests
are required in some patients for evaluating their fitness
for surgery. These tests include:
Spirometry
Lung Volumes
Diffusion Capacity
Exercise Challenge
Methacholine Challenge
Tests
Relating to Nerves and Muscles
Nerve Conduction Studies (NCS) and needle electromyography
(EMG) play a central role in the evaluation of neuromuscular
disorder. These tests are often used to diagnose disorders
of peripheral nervous system. In addition, these studies
can also provide useful diagnostic information in disorders
of the central nervous system.
Electromyography (EMG)
Nerve Conduction Studies
(NCS)
Test
Relating to the Brain
Electro encephalography is the neurophysiological measurement
of the electrical activity of the brain by recording
from electrodes placed on the scalp. The resulting traces
are represented by brain waves. This procedure is used
to diagnose epilepsy, brain damage and other neurological
problems.
Please note that only CGH doctors can
refer these tests for our inpatients and outpatients,
except for 12 leads ECG.
