Diagnostic Services

DOCS VIP Clinic was designed to meet the medical needs of our great nation through a team of highly skilled doctors, nurses, and medical technicians. DOCS VIP Clinic originated with the desire of the founding physicians to develop both their own range of services as well as the ability to provide these services to communities throughout Nigeria.

Here at DOCS VIP Clinic we provide all these great diagnostic services:

Electrocardiography (ECG)

Electrocardiography is a transthoracic (across the thorax or chest) interpretation of the electrical activity of the heart over a period of time, as detected by electrodes attached to the surface of the skin and recorded by a device external to your body. The recording produced by this non-invasive procedure is termed an electrocardiogram (also ECG or EKG).

An ECG is done to measure:

  • The rate and regularity of your heartbeat.

  • The size and position of your heart chambers.

  • The presence of any damage to your heart.

  • The effects of drugs or devices used to regulate the heart, such as a pacemaker.

Cardiac Stress Testing

Cardiac stress testing are tests performed by a doctor and/or trained technician to determine the amount of stress that your heart can manage before developing either an abnormal rhythm or evidence of ischemia (not enough blood flow to the heart muscle). The most commonly performed cardiac test is the exercise stress test. The exercise stress test is a test used to provide information about how the heart responds to exertion. It usually involves walking on a treadmill or pedaling a stationary bike at increasing levels of difficulty, while your electrocardiogram, heart rate and blood pressure are monitored.

Cardiac stress tests are done to:

  • Evaluate the effectiveness of your heart medications to control angina and ischemia.

  • Determine the likelihood of having coronary heart disease and the need for further evaluation.

  • Check the effectiveness of procedures done to improve blood flow within the heart vessels in people with coronary heart disease.

  • Identify abnormal heart rhythms.

  • Help you develop a safe exercise program.


Reflected sound waves are used to evaluate blood as it flows through a blood vessel. It helps doctors evaluate blood flow through the major arteries and veins of the arms, legs, and neck. It can show blocked or reduced blood flow through narrowing in the major arteries of the neck that could cause a stroke. It also can reveal blood clots in leg veins (deep vein thrombosis, or DVT) that could break loose and block blood flow to the lungs (pulmonary embolism). During the ultrasound, a handheld instrument (transducer) is passed lightly over the skin above a blood vessel. The transducer sends and receives sound waves that are amplified through a microphone. Information from the reflected sound waves can be processed by a computer to provide graphs or pictures that represent the flow of blood through the blood vessels. These graphs or pictures can be saved for future review or evaluation.

This ultrasound is done to:

  • Detect blood clots and blocked or narrowed blood vessels in almost any part of the body, especially in the neck, arms, and legs. Blocked or narrowed arteries of the neck can cause dizziness, loss of vision, paralysis, weakness, numbness, or other symptoms of a stroke. Blood clots in the deep veins of the leg can cause leg pain and swelling and can increase a person's risk of pulmonary embolism.

  • Evaluate leg pain that may be caused by intermittent claudication, a condition caused by atherosclerosis of the lower extremities.

  • Evaluate blood flow after a stroke or other condition that might be caused by a problem with blood flow. Evaluation of a stroke can be done through a technique called Transcranial Doppler (TCD) Ultrasound.

  • Map veins that may be used for blood vessel grafts. It also can evaluate the condition of grafts used to bypass blockage in an arm or leg.

  • Determine the amount of blood flow to a transplanted kidney or liver.

  • Determine the presence, amount, and location of arterial plaque. Plaque in the carotid arteries can reduce blood flow to the brain and may increase the risk of stroke.


Echocardiography is a non-invasive, safe and effective test to study the anatomy of the heart. It uses sound waves (ultrasound) to form images of the structures of the heart. The ultrasound and electrocardiography (ECG) signals are recorded on a videotape simultaneously to be reviewed by the cardiologist. The test can evaluate the size of the different chambers of the heart, the quality of the valves, measure the heart's pumping ability and identify other problems of the heart that may increase a person's risk for dangerous arrhythmias.

Echocardiography is performed to:

  • Determine the size of the chambers of your heart, which can change with conditions such as hypertension, heart damage as a result of myocardial infarction or congestive heart failure.

  • Determine the heart's pumping ability.

  • Identify the structure, thickness and movement of the heart valves.

  • Determine if there is fluid, blood clots or tumors in specific areas of the heart.

24 Hour Ambulatory Blood Pressure Monitoring (ABPM)

DOCS 24 hour ABPM provides an accurate reading of your overall blood pressure and can help you to significantly reduce the risk of cardiovascular diseases. High blood pressure is the leading cause of cardiovascular diseases such as a stroke or heart attack. Some of these diseases can be avoided with proper blood pressure monitoring and control. The regular one-off clinical blood pressure measurement technique does not provide an accurate reading of your overall blood pressure and can potentially lead to a misdiagnosis of up to 45%.

Night-time blood pressure monitoring is very important because it identifies people known as non-dippers who are at high risk of a cardiovascular event. Only DOCS 24 hour ABPM gives you the ability to monitor your blood pressure around the clock for 24 hours and shows accurate reading.

Benefits of DOCS 24 ABPM:

  • DOCS 24 ABPM gives better and more measurements than conventional techniques. The real blood pressure is reflected more accurately by repeated measurements.

  • Rather than a synopsis of your blood pressure, DOCS 24 ABPM shows blood pressure behaviour over a 24-hour period.

  • DOCS 24 ABPM can identify people with abnormal patterns of nocturnal blood pressure which are associated with cardiovascular diseases.

  • DOCS 24 ABPM helps you to better control your blood pressure.

24 Hour Holter Monitoring

Our Holter monitoring is a continuous tape recording of your EKG for 24 hours or more. Since you can wear it during your regular daily activities, it helps the physician correlate symptoms of dizziness, palpitations (a sensation of fast or irregular heart rhythm) or black outs. Since the recording covers 24 hours or more, on a continuous basis, Holter monitoring is much more likely to detect an abnormal heart rhythm when compared to the EKG which lasts less than a minute. It can also help evaluate your EKG during episodes of chest pain, during which time there may be tell tale changes to suggest ischemia (pronounced is-keem-ya) or reduced blood supply to the muscle of the left ventricle.

The only requirement is that you wear loose-fitting clothes. Buttons down the front of a shirt or blouse is preferable. This makes it convenient to apply the EKG electrodes, and also comfortably carry the monitor in a relatively discreet manner. A report is provided to your physician, together with multiple EKG strips after the tape has been scanned by the technician. If the technician sees a rhythm that is life-threatening or potentially dangerous the physician is informed immediately. Otherwise, it may take a few days before you get the official results from your physician's office. At that time, you may also receive additional recommendations based upon the results of the test, for example, a pacemaker may be recommended if a patient has blackouts and the Holter monitor shows a seriously slow heart beat during the test.

Pulmonary Function Testing

Pulmonary function testing evaluates how well your lungs work. The tests are done to determine how much air your lungs can hold, how quickly you can move air in and out of your lungs, and how well your lungs add oxygen and remove carbon dioxide from your blood. The tests can diagnose lung diseases and measure the severity of lung problems.

Pulmonary function tests are done to:

  • Determine the cause of breathing problems.

  • Diagnose certain lung diseases, such as asthma or Chronic Obstructive Pulmonary Disease (COPD).

  • Evaluate your lung function before surgery.

  • Monitor the lung function of a person who is regularly exposed to substances such as asbestos or radon that can damage the lungs.

  • Monitor the effectiveness of treatment for lung diseases.

Preventive Health Screening

At DOCS VIP Clinics, you can be proactive about your health by staying on top of necessary screenings and health care visits. Regular physical exams and health screening tests are important part of preventative healthcare. Your test results provide a snapshot of your current health and reveal opportunities to make healthy choices. Screening test can help ensure that common and serious diseases are detected early which is often the key to successful diagnosis.

DOCS VIP Clinics preventive health screenings are extremely affordable. We offer periodic physical exams, and recommended lab work.
