Cardiologists Explained: What They Do and When You Should See One

When something does not feel quite right with your heart, it is understandable to have questions. You may have experienced chest discomfort, palpitations, breathlessness or unusual tiredness, or perhaps your GP has recommended seeing a specialist.

At Westbourne Medical Studios, we understand that being referred to a cardiologist can feel daunting. Our aim is to make the process straightforward, reassuring and focused on you.

In this guide, we explain what a cardiologist does, the conditions they can help with and when it may be appropriate to arrange a cardiology assessment.

A cardiologist is a doctor who specialises in the heart and cardiovascular system, including the blood vessels.

You may hear the terms ‘heart specialist’ and ‘cardiologist’ used interchangeably. They both refer to a doctor with specialist expertise in diagnosing, monitoring and treating conditions affecting the heart and circulation.

Cardiologists can assess a wide range of symptoms and conditions, from heart rhythm problems and high blood pressure to coronary artery disease and heart valve conditions.

They can also provide advice about managing cardiovascular risk and maintaining good heart health.

You do not necessarily need to wait until you have a diagnosed heart condition before seeing a cardiologist. Sometimes, an assessment can provide reassurance or help identify a potential issue at an earlier stage.

Your GP may recommend a cardiology referral if you have symptoms or test results that require further investigation. You can also seek private cardiology care if you have concerns about your heart and would like a specialist assessment.

There are several symptoms that can warrant further assessment, particularly if they are persistent, recurring or unexplained.

These can include:

• Chest pain or discomfort
• Heart palpitations or a racing, fluttering or irregular heartbeat
• Breathlessness, particularly during activity
• Dizziness or fainting
• Unexplained tiredness or reduced exercise tolerance
• Swelling in the legs or ankles

These symptoms can have many possible causes and do not necessarily mean you have a heart condition. However, speaking to a healthcare professional can help establish what may be causing them.

If you are experiencing sudden or severe chest pain, severe difficulty breathing, loss of consciousness or other symptoms that could indicate a medical emergency, seek urgent medical attention rather than waiting for a private cardiology appointment.

When you see a cardiologist, your appointment will usually begin with a detailed discussion about your symptoms, medical history, lifestyle and any relevant family history.

We believe this conversation is an important part of your care. Understanding what you have been experiencing helps your cardiologist decide whether further investigations are appropriate.

Depending on your symptoms and circumstances, your cardiologist may recommend tests such as an electrocardiogram (ECG), echocardiogram, blood pressure monitoring or other cardiac investigations.

These tests can help assess how your heart is functioning and identify changes that may require further attention.

Cardiologists can investigate and manage many different heart-related conditions.

These include abnormal heart rhythms, known as arrhythmias, as well as coronary artery disease, high blood pressure, heart valve problems and some forms of heart failure.

They can also assess patients who have a family history of certain heart conditions or who have cardiovascular risk factors.

Early assessment can sometimes provide reassurance, while in other cases it may identify an issue that benefits from monitoring or treatment.

At Westbourne Medical Studios, we want your experience to feel personal from the moment you arrive.

We provide a calm, welcoming environment where you can discuss your concerns openly and have time to ask questions. We understand that heart symptoms can be worrying, so we take the time to explain what we are doing and why.

Your cardiology appointment will be centred around your individual circumstances rather than a one-size-fits-all approach.

If further tests or treatment are recommended, we will explain the next steps clearly, helping you understand your options and what they mean for you.

Knowing when to seek specialist advice can be difficult, particularly when symptoms are intermittent or relatively mild.

If you have concerns about your heart, we encourage you to speak to a healthcare professional rather than trying to diagnose yourself.

At Westbourne Medical Studios, our cardiology service is designed to provide expert assessment in a supportive, patient-focused setting.

Whether you have been advised to see a cardiologist or would like to discuss unexplained symptoms, we are here to help you understand your heart health and the options available to you.

Your heart deserves attention, and getting the right advice can give you greater clarity and confidence about your health.

What is the difference between a cardiologist and a GP?

A GP provides care across a broad range of health conditions, while a cardiologist specialises specifically in the heart and cardiovascular system. Your GP may recommend seeing a cardiologist if your symptoms or test results require specialist assessment.

What symptoms should I discuss with a cardiologist?

Chest discomfort, palpitations, unexplained breathlessness, dizziness, fainting and reduced exercise tolerance can all warrant medical assessment. These symptoms can have many causes, so a cardiologist can help investigate them appropriately.

What tests might a cardiologist perform?

Depending on your symptoms, your cardiologist may recommend an ECG, echocardiogram, blood pressure monitoring or other investigations. Your cardiologist will explain which tests are appropriate and why.

Do I need a GP referral to see a private cardiologist?

Referral requirements can vary depending on the service and your circumstances. If you are considering a private cardiology appointment at Westbourne Medical Studios, you do not require a referral to see our cardiologist, Dr Karen J Hogg. Our team can explain the process and help you understand what you need before your appointment.
