What is ECG testing?

ECG stands for electrocardiogram. It is a quick, simple and non-invasive test which records the heart’s rate, rhythm and electrical activity.

ECG testing takes place in the comfort and privacy of the London Medical outpatient clinic. An ECG is usually one of the first tests performed at the clinic, it can provide useful information; however, further, more detailed cardiac investigations are usually also required.

Sticky patches are attached to your chest, arms and legs. These electrodes are connected with wires to the ECG machine. The device picks up the heart’s electrical activity and prints the trace onto paper for analysis. The test is painless and only takes a few minutes.

The ECG can help your consultant identify abnormalities with your heart’s rate or rhythm. It can also show if you’re having a heart attack or if you’ve previously had a heart attack.

London Medical offers different types of ECG tests to investigate your heart over a prolonged period or to assess its activity when it is being stressed during exercise.

Ambulatory ECG or Holter monitoring

Ambulatory ECG monitoring can be used to record your heart’s electrical activity over 24 to 48 hours. It can help identify abnormalities in the heart's activity that may be intermittent such as episodes of atrial fibrillation or skipped beats.

Three sticky electrodes are attached to your chest and connected to a small portable recording device. The recorder is worn on a belt around your waist for 24-48 hours before being returned to London Medical for expert analysis. You can be fully mobile and able to get on with normal life, however you should avoid getting the device wet so no bathing, swimming or showering is allowed.

What is an echocardiogram?

An echocardiogram, called an ‘echo’ for short, is a type of ultrasound scan of the heart. It’s a painless, safe and non-invasive test that uses sound waves to create a moving image of your heart.

The specialist sonographers can visualise the structures within your heart, so that any congenital abnormalities, defects in the walls or valve problems can be identified.

An echo may be arranged if you have heart failure or following a heart attack. The scan provides detailed information about your heart’s function and how well it is pumping blood. The sonographer can measure the amount of blood that is pumped out of the left ventricle in the heart with each beat. This ‘ejection fraction’ is expressed as a percentage, with anything over 50 percent of the blood considered normal.

What to expect from an echocardiogram at London Medical

Echo testing takes place in the comfort and discretion of the London Medical outpatient clinic. You will be positioned on a couch and given a hospital gown so that the sonographer can apply the probe to your chest wall.

The sonographer will move the probe over your chest to see different parts of your heart. Gel is applied to the device to aid sound wave transmission. It may feel cold and sticky, but should be completely pain-free. The whole procedure takes between 15 minutes and an hour.

Depending on your history and examination results, your cardiology consultant may arrange specialist echocardiograms to provide more detailed information.

Specialist echocardiograms at London Medical

Transoesophageal echocardiogram (TOE)

A transoesophageal echocardiogram scans the heart from your oesophagus or gullet. This can provide clearer images because the probe gets nearer certain structures in the heart.

A local anaesthetic spray is used to numb your throat and you will be offered a light sedative to help you relax. You will then be asked to swallow a fine probe, which will provide close up images of your heart.

Stress echocardiogram

A stress echo can help identify coronary heart disease. It is performed when the heart is beating faster. The procedure is carried out while you are exercising on a treadmill or exercise bike. If you are unable to exercise because of illness or injury, the heart rate can be raised with medication.

Bubble echocardiogram

A bubble study is an echo designed to identify holes in the heart. A small volume of saline is injected through one of the veins in your arm into your bloodstream.

Tiny bubbles within the saltwater can be seen on the scan images so that defects in the heart walls (either congenital or following heart attack or surgery) can be located.

Expert analysis and treatment

The ECG or echo test is just the first step; the expert physicians at London Medical can help you understand the results, explain your personal heart health and work with you to make changes to prevent heart disease, stroke, and premature death.

Frequently Asked Questions

Will I be awake for the testing?

ECG and standard echocardiograms are painless and do not require sedation or anaesthetic. A transoesophageal echo requires a local anaesthetic spray to numb the throat. A light, short-acting sedative will also be offered, however many people prefer to have the test without any medication.

Are the tests painful?

ECG testing is totally painless and quick. During an echo you will feel some pushing and pressure and the gel is cold and sticky, however, it should be a pain-free.

What is the preparation for transoesophageal echo?

For your transoesophageal echo, you should have an empty stomach. It’s important not to eat on the day of the procedure. The food and drink guidance will depend on the time of your investigation, the specialist team at London Medical will provide individual advice on what you can eat and drink and when.

Chest pain, angina and coronary artery disease (CAD)

Coronary artery disease (CAD) is a type of cardiovascular condition in which the vessels that supply blood to the heart become constricted by fatty deposits. The buildup of these fatty deposits is called atherosclerosis. CAD is commonly referred to as coronary heart disease, which is the most common form of heart disease

Symptoms

Chest pain (upon exercise)

Conditions

Angina

Tests

Echocardiogram (inc. trans-thoracic and stress echo)

Cardiac MRI

Resting ECG

Treatments

Percutaneous coronary intervention

Heart failure (HF)

Heart failure is a long-term condition in which the heart is unable to pump blood throughout the body as it should. Your body depends on the heart to supply oxygen-rich and nutrient-rich blood to the body’s cells.

Symptoms

Breathlessness (when walking up hill/stairs/upon exercise)

Conditions

Heart failure

Oedema

LV fibrosis

Tests

Echocardiogram (inc. trans-thoracic and stress echo)

Resting ECG

Treatments

Implantable cardioverter-defibrillator (ICD)

Cardiac Resyncronicization Therapy (CRT)

Valvular Heart Disease (VHD)

Your heart has four heart valves that control the flow of blood in one direction. If you have valvular heart disease, it means one or more of these valves are not working as they should. This can cause problems with your blood flow, putting extra strain on your heart to work harder.

Symptoms

Breathlessness (when walking up hill/stairs/upon exercise)

Conditions

Aortic/Heart valve disease/stenosis (inc. Mitral valve regurgitation)

Tests

Echocardiogram (inc. trans-thoracic and stress echo)

Resting ECG

Holter ECG

Exercise test

Treatments

TAVI

SAVR

Mitraclip

Valve replacement/reconstruction

 

Cardiac Arrhythmias (CA)

Your heartbeat is controlled by electrical impulses. It’s normal for us to experience changes in our heartbeat at different times of the day depending on our activities. But if you have an arrhythmia, it means that the electrical activity that controls your heartbeat is affected.

Symptoms

Palpitations

Dizziness

Syncope

Conditions

Atrial fibrillation

Heart/AV Block

Tachycardia (inc. Ventricular Tachycardia (VT runs) and Superventricular tachycardia)

Bradycardia

Tests

Resting ECG

Holter ECG

Echocardiogram (inc. trans-thoracic and stress echo)

Treatments

Beta blockers

Cardioversion

Pacemaker

Anticoagulants

Cardiac ablation

ICD implantation

Arterial Hypertension

Blood pressure is the pressure of your blood pushing against your arteries. Your blood pressure naturally goes up and down throughout the day. Hypertension is the medical term for when your blood pressure numbers are consistently too high.

Symptoms

High blood pressure

Unusual Hypertension

Endocrine hypertension

Ordinary hypertension

Tests

Echocardiogram (inc. trans-thoracic and stress echo)

24h Ambulatory Blood Pressure Monitoring

Treatments

Diet:

Low salt DASH diet

Drugs:

Calcium channel blockers

ACE-inhibitors

Beta blockers

Renal nerve ablation for severe resistant hypertension

High Cholesterol

Cholesterol is a fatty substance in our blood that is produced naturally in our liver. It is essential for your body’s normal functioning – it is used by our cells to make some hormones and vitamin D. Cholesterol can also be found in the foods we eat. Over time, if your blood cholesterol levels are too elevated, it can pose a serious risk to your health.

Symptoms

None

Conditions

Monogenic Familial hyperlipidaemia

Polygenic hyperlipidaemia

Dyslipidaemia (low HDL, high LDL, raised triglyceride)

Familial combined hyperlipidaemia

Rare lipid disorders

Tests
