Tests for your Heart

Cardiac Testing

Getting the right heart test for you

Choosing the right tests for you can make all the difference.  Each test has its own merits and they are complementary to each other.

To fully understand your health, Dr Nijjer may need to organise one or more tests.  Dr Nijjer will take the time to explain what these tests are, what they will involve and how they will help get to the bottom of your problem.

Cardiac Testing

Common cardiac tests that can give us a detailed assessment of your heart health

An Electrocardiogram can tell us about your cardiac rhythm and detect cardiac ischaemia


A 12-Lead ECG can help diagnose your heart rhythm and look for underlying heart disease.

Can Echocardiogram can directly assess your heart valves


Echocardiography uses ultrasound to see the heart muscle and valves; it is used to monitor heart function.

An ECG Monitor can detect intermittent arrhythmia

Holter Monitoring

ECG monitoring can be performed over 24 hours to up to 14 days to diagnose the cause of palpitations

High blood pressure is a cause of heart disease

Blood Pressure

Ambulatory Blood Pressure Monitoring (ABPM) is the gold standard test to identify true hypertension

Cardiac CT can visualise the coronary arteries in a non-invasive way

Cardiac CT

CT Coronary Angiography can reveal the build up of coronary disease - made up of cholesterol and calcium. It is fast and painless.

Cardiac MRI allows us to see the heart in exquisite detail

Cardiac MRI

A cardiac MRI is used to perform detailed assessment of the heart muscle. It can assess for cardiac scarring, thickening or infarction.

Cardiac catheterisation can identify coronary disease

Coronary Angiography

Invasive coronary angiography is the gold standard test to assess the heart arteries. It is often a day case test.

Pressure wire studies measure blood flow in the arteries

Coronary Pressure Wire

Invasive pressure wire studies are the gold standard for deciding whether coronary stents are needed.

Exercise Stress Testing

Exercise Testing

An exercise tolerance test (ETT) involves continuous ECG reading while you run on a treadmill. It can assess exercise capacity and can be important for certain jobs.

Stress Echo

Either exercise or a medicine is used to increase the heart rate and then the heart is scanned using an echocardiogram. It can detect cardiac ischaemia.

Breathing can be assessed by MVO2 Testing

MVO2 Testing

MVO2 testing is a highly specialised test to detect the causes of breathlessness. Exercise is performed while measuring oxygen and carbon dioxide levels.

Tilt Testing

Tilt Table Testing

Patients with recurrent fainting spells can have changes in blood pressure and heart rate measured by altering the body position.

Dobutamine stress echocardiography (DSE) is a type of stress test used to help investigate pains in the chest or to look for ‘cardiac ischaemia’.  This is when the heart suffers from an insufficient blood supply.

Stress Perfusion MRI

A stress perfusion MRI test is a specialist test that looks for scaring in the heart and evidence of an insufficient blood supply to the heart.  When there are narrowings of the heart arteries, it can be detected by looking for changes on a stress perfusion MRI.

Coronary angiography

A coronary angiogram is an invasive procedure which gives us the clearest and most direct look at the coronary arteries.  These are the arteries that nourish the heart muscle and when they become narrowed from atherosclerosis, it leads to a central tightness across the chest called angina.

Coronary Angioplasty

Coronary Angioplasty is the treatment of coronary blockages by balloon dilatation followed by insertion of a drug-eluting stent.  This treatment can improve the blood flow in heart arteries and improve symptoms. In patients having heart attacks, it is life-saving.

Ablation can treat atrial fibrillation and other arrhythmia

EPS and ablation

EPS – Electrophysiology Study and ablations are performed for patients who have recurrent palpitations caused by specific arrhythmias, including atrial fibrillation, supraventricular tachycardias and ventricular tachycardias. If we detect certain arrhythmias then a procedure can be performed through a large vein in you leg. This allows us to reach the heart and burn away the offending parts of the heart causing the issue.
