Clinical Physiology Testing for Heart, Brain, Lung and Other Body Functions
Your body is constantly working—even when you are resting.
Your heart is pumping blood, your lungs are moving oxygen in and out of your body, your brain is producing electrical activity, and your eyes and other organs are carrying out complex functions that are essential to everyday life.
Clinical physiology is the area of healthcare that uses specialized tests to assess how different parts of the body are functioning.
At LifeWay Diagnostics in Owerri, our Clinical Physiology services provide patients and healthcare professionals with access to a range of functional diagnostic investigations, including Electrocardiography (ECG), Echocardiography, Electroencephalography (EEG), Spirometry, Holter Monitoring, Ambulatory Blood Pressure Monitoring and Optical Coherence Tomography (OCT).
These investigations can provide valuable information that helps healthcare professionals assess symptoms, investigate suspected conditions, monitor existing conditions and make informed clinical decisions.
If your doctor has requested a cardiac, neurological, respiratory or other physiological investigation, our team can guide you through the appropriate examination.

What Is Clinical Physiology?
Clinical physiology focuses on measuring and assessing how the body’s organs and systems function.
Unlike some imaging examinations that primarily show the physical structure of an organ, physiological investigations can provide information about how that organ is working.
For example:
An ECG records the electrical activity of the heart.
Echocardiography uses ultrasound to assess the structure and function of the heart.
An EEG records electrical activity in the brain.
Spirometry measures aspects of breathing and lung function.
Holter monitoring records the heart’s electrical activity over an extended period.
Ambulatory blood pressure monitoring measures blood pressure at intervals during normal daily activities.
OCT produces detailed cross-sectional images of structures within the eye.
These tests can be performed for different reasons depending on the patient’s symptoms, medical history and doctor’s assessment.

Each investigation serves a different purpose. Your doctor or healthcare provider can recommend the test that is most appropriate for your symptoms and clinical needs.
Electrocardiography (ECG)
ECG Testing in Owerri
An electrocardiogram, commonly called an ECG, is a test that records the electrical activity of the heart.
Every heartbeat is controlled by electrical signals. An ECG captures these signals through electrodes placed on the skin and produces a tracing that can be reviewed by an appropriately trained healthcare professional.
An ECG is a quick and commonly used cardiac investigation.
Why Might You Need an ECG?
A doctor may request an ECG when investigating symptoms such as:
Chest discomfort
Palpitations
Fast or irregular heartbeat
Shortness of breath
Dizziness
Fainting or near-fainting
Unexplained weakness or fatigue
An ECG may also be used as part of an assessment for people with known or suspected heart conditions.
What Happens During an ECG?
You will usually lie down while small electrodes are placed on specific areas of your chest and limbs.
The electrodes detect the electrical activity of your heart.
The recording itself is generally quick and does not involve injections or cutting the skin.
It is important to remain still during the recording because movement can interfere with the signal.
Is an ECG Painful?
An ECG is generally painless.
The electrodes are placed on the skin and then removed after the recording.
Some people may experience minor discomfort when an adhesive electrode is removed, particularly if they have sensitive skin.
Echocardiography
Echocardiogram Services in Owerri
An echocardiogram, commonly called an echo, is an ultrasound examination of the heart.
It uses sound waves to create moving images of the heart, allowing healthcare professionals to assess its structure and certain aspects of how it functions.
Unlike an X-ray, echocardiography does not use ionizing radiation.
What Can an Echocardiogram Assess?
Depending on the type of examination and the clinical question, echocardiography can provide information about:
The chambers of the heart
Heart valves
Heart muscle movement
Heart pumping function
Blood flow through the heart
Certain structural abnormalities
The surrounding structures of the heart
Why Might a Doctor Request an Echocardiogram?
An echocardiogram may be requested when a doctor needs to investigate or monitor conditions affecting the heart.
It may be considered when a patient has symptoms such as:
Breathlessness
Chest discomfort
Swelling of the legs
Palpitations
Fatigue
Fainting or dizziness
It may also be requested when a doctor hears an abnormal heart sound or needs to monitor an already diagnosed heart condition.
What Happens During an Echocardiogram?
You will normally lie on an examination bed.
A small amount of ultrasound gel is applied to the skin of your chest.
The sonographer or healthcare professional moves an ultrasound probe across specific areas of the chest to obtain images of the heart.
You may be asked to change position or briefly hold your breath during parts of the examination.
The examination is generally non-invasive.
Electroencephalography (EEG)
EEG Testing in Owerri
An electroencephalogram (EEG) is a test used to record the electrical activity of the brain.
The brain communicates through electrical activity, and an EEG allows healthcare professionals to record this activity using electrodes placed on the scalp.
Why Is an EEG Performed?
An EEG may be requested when a doctor is investigating certain neurological symptoms or conditions.
It can be particularly relevant in the assessment of episodes such as:
Seizures
Unexplained blackouts
Loss of awareness
Certain unusual movements
Some sleep-related concerns
Other symptoms requiring neurological evaluation
The decision to perform an EEG is made according to the patient’s clinical circumstances.
What Happens During an EEG?
Small electrodes are placed on the scalp using appropriate equipment.
The electrodes detect electrical activity produced by the brain.
During the examination, you may be asked to relax and remain still. Depending on the type of EEG being performed, you may also be asked to carry out certain activities such as opening and closing your eyes or breathing in a particular way.
Some EEG examinations may involve sleep or additional monitoring depending on the doctor’s request.
Does an EEG Hurt?
An EEG is non-invasive and does not normally cause pain.
The electrodes record electrical activity; they do not send electricity into your brain.
Spirometry
Lung Function Testing in Owerri
Spirometry is a common pulmonary function test used to assess how well the lungs are working.
During spirometry, you breathe into a device called a spirometer.
The equipment measures aspects of your breathing, including how much air you can move and how quickly you can breathe it out.
Why Might You Need Spirometry?
Your doctor may recommend spirometry if you have symptoms such as:
Persistent cough
Wheezing
Shortness of breath
Chest tightness
Reduced exercise tolerance
It may also be used when a healthcare professional needs to investigate or monitor certain respiratory conditions.
What Happens During Spirometry?
You will usually sit comfortably while the healthcare professional explains the procedure.
You will breathe through a mouthpiece connected to the spirometer.
You may be asked to take a deep breath and then breathe out as forcefully and completely as possible.
You may need to repeat the manoeuvre several times so that reliable measurements can be obtained.
How Should I Prepare for Spirometry?
Preparation can depend on the reason for your test and any medication you use.
Your healthcare provider may provide specific instructions about medications, smoking, exercise or eating before the examination.
Follow the instructions given to you before the test.
Holter Monitoring
Holter Monitoring in Owerri
A Holter monitor is a portable device that records the heart’s electrical activity continuously over an extended period.
Unlike a standard ECG, which records the heart for a short period while you are at the diagnostic centre, Holter monitoring allows your heart rhythm to be recorded while you go about your normal activities.
This can be useful when symptoms occur intermittently and may not happen during a short ECG.
Why Might You Need Holter Monitoring?
Your doctor may recommend Holter monitoring if you experience:
Intermittent palpitations
Episodes of rapid heartbeat
Irregular heartbeat
Dizziness
Fainting or near-fainting
Symptoms that come and go
It may also be used to monitor certain known heart rhythm problems or assess how the heart responds to treatment.
What Happens During Holter Monitoring?
Small electrodes are attached to your chest and connected to a portable recording device.
You will normally wear the monitor for the period recommended by your healthcare provider.
You can generally continue many of your normal daily activities, although you will receive instructions about keeping the device and electrodes safe.
You may also be asked to record symptoms or activities in a diary so that they can be compared with the recorded heart rhythm.
Ambulatory Blood Pressure Monitoring
24-Hour Blood Pressure Monitoring in Owerri
Ambulatory Blood Pressure Monitoring (ABPM) is a method of measuring blood pressure at regular intervals while you go about your normal daily activities.
Instead of relying only on a single blood pressure measurement taken at a clinic, ambulatory monitoring provides multiple readings over a longer period.
This can give your healthcare provider a broader picture of how your blood pressure behaves throughout the day and, depending on the monitoring schedule, during sleep.
Why Might ABPM Be Recommended?
Your doctor may recommend ambulatory blood pressure monitoring when they need more information about your blood pressure patterns.
It may be useful when assessing situations such as:
Repeatedly elevated blood pressure readings
Possible hypertension
Differences between clinic and home blood pressure readings
Blood pressure changes throughout the day
Response to blood pressure treatment
What Happens During ABPM?
A blood pressure cuff is placed around your upper arm and connected to a small portable monitor.
The device automatically takes blood pressure readings at predetermined intervals.
You can continue your normal activities as advised by your healthcare provider.
The monitoring period is usually determined by your doctor or healthcare team.
Optical Coherence Tomography (OCT)
OCT Eye Imaging in Owerri
Optical Coherence Tomography (OCT) is a non-invasive imaging examination that produces detailed cross-sectional images of structures within the eye.
It uses light rather than X-rays to create high-resolution images.
OCT can provide detailed information about structures such as the retina and optic nerve, depending on the examination performed.
Why Is OCT Performed?
An eye specialist may recommend OCT when evaluating or monitoring certain eye conditions.
It can provide useful information when assessing changes involving the retina, optic nerve and other structures within the eye.
OCT may be used as part of an ophthalmic assessment or to monitor an existing eye condition over time.
What Happens During an OCT Examination?
You will sit in front of the OCT equipment and position your head appropriately.
The device captures images of the eye without touching it.
You will be asked to look at a target while the images are obtained.
The examination is generally quick and non-invasive.
Is OCT Painful?
OCT is generally painless.
There are no injections or surgical procedures involved in a standard OCT scan.
Who May Need Clinical Physiology Testing?
Clinical physiology investigations may be recommended for people experiencing specific symptoms or for patients who need monitoring of an existing condition.
Depending on the investigation, your doctor may recommend testing for symptoms such as:
Chest discomfort
Palpitations
Shortness of breath
Dizziness
Fainting
Persistent cough
Wheezing
Breathing difficulties
Seizure-like episodes
Unexplained changes in consciousness
Abnormal blood pressure readings
Certain eye or vision concerns
Testing may also be recommended as part of ongoing medical monitoring.
Not everyone with these symptoms will require the same test. The appropriate investigation depends on your clinical history and your healthcare provider’s assessment.
Clinical Physiology for Medical Assessment and Monitoring
Clinical physiology tests can serve several purposes.
Investigation
Testing may help healthcare professionals investigate symptoms and determine what additional evaluation may be appropriate.
Diagnosis
Physiological measurements can provide information that contributes to the diagnosis of certain conditions.
Monitoring
Patients with known conditions may require repeat testing to monitor changes over time.
Treatment Assessment
Some investigations can provide information that helps healthcare professionals assess a patient’s response to treatment.
Pre-Procedure Assessment
In selected situations, physiological investigations may be requested before certain medical procedures.
The purpose of every test depends on the patient’s individual clinical situation.
What Should I Bring for My Appointment?
If you have been referred for a Clinical Physiology investigation, bring any relevant information that may help the healthcare team.
This may include:
Doctor’s referral or request
Previous test reports
Previous ECG or cardiac reports
Previous imaging reports
List of current medications
Relevant medical records
Information about your symptoms
If you are undergoing a follow-up examination, previous results can sometimes be useful for comparison.
Before Your Clinical Physiology Test
Preparation depends on the specific examination.
Some tests require little or no preparation, while others may have specific instructions.
For example:
ECG generally requires simple preparation.
Echocardiography usually requires little preparation for a standard examination.
EEG preparation may vary depending on the type of EEG.
Spirometry may require specific instructions regarding medication or other activities.
Holter monitoring requires preparation for wearing the recording device.
ABPM requires the monitor to be worn throughout the monitoring period.
OCT generally requires minimal preparation.
Always follow the instructions provided for your specific test.
If you are unsure, contact LifeWay Diagnostics before your appointment.
Is Clinical Physiology Testing Safe?
Many Clinical Physiology investigations are non-invasive and do not involve ionizing radiation.
For example:
ECG records electrical activity from the skin.
Echocardiography uses ultrasound.
EEG records brain electrical activity through scalp electrodes.
Spirometry measures breathing.
Holter monitoring records heart rhythm through skin electrodes.
ABPM uses a blood pressure cuff.
OCT uses light to create images.
Your healthcare professional can explain any specific considerations associated with your particular investigation.
What Happens After the Test?
After your investigation, the recorded measurements or images are reviewed as part of the diagnostic process.
Depending on the test, a report may be prepared for your referring doctor or healthcare provider.
Your doctor can then consider the results alongside:
Your symptoms
Medical history
Physical examination
Previous test results
Other investigations
A physiological test should therefore be understood as one part of a broader medical assessment.
