Symptoms & Conditions
When to See Dr Nijjer
Chest Pain & Discomfort
A central chest discomfort moving into the neck or arm can be a feature of heart disease. Seek expert assessment to identify the cause.
Learn more →Palpitations
A racing heartbeat, thudding, or skipping can signify cardiac arrhythmia. ECG monitoring identifies the underlying cause.
Learn more →High Blood Pressure
The silent killer. Blood pressure remains the number one cause of death globally. Holistic approaches are most effective when tackled early.
Learn more →Breathlessness
Breathlessness when active, when lying flat, or waking from sleep can indicate heart muscle weakness. Echocardiography provides detailed assessment.
Learn more →High Cholesterol
Cholesterol levels contribute to atherosclerosis or artery disease. Diet, exercise and medication can reduce long-term risk significantly.
Learn more →Coronary Artery Disease
Narrowing of the heart arteries causes reduced blood flow. Specialist intervention including stenting or bypass surgery may be required to restore circulation.

Precision Diagnostics
& Expert Intervention
Dr Nijjer offers a comprehensive range of cardiac investigations and complex interventional procedures, available at NHS and private sites across London.
ECG & Monitoring
12-lead ECG, 24-hour Holter and up to 14-day monitoring to diagnose arrhythmias and palpitations.
Echocardiography
Ultrasound imaging of the heart muscle and valves to assess cardiac function and detect disease.
CT Coronary Angiography
Non-invasive technique to assess for coronary artery disease without the need for an invasive procedure.
Coronary Physiology
iFR and pressure wire assessment — technology developed by Dr Nijjer himself — to guide intervention decisions.
Intravascular Imaging
Optical coherence tomography (OCT) to visualise vessel structure and guide precise stent placement.
Coronary Angioplasty
Complex coronary intervention including Laser and Rotablation for calcified or complex lesions.
Pacemaker Implantation
Insertion of pacemaker devices for patients with slow heart rhythms, including complex device management.
Heart Loop Recorders
Internal cardiac monitoring devices for patients with fast or racing heart beats where external monitoring is insufficient.
Cardiac MRI
Gold-standard imaging of heart structure, function and scarring — including stress perfusion CMR for ischaemia and viability assessment.
