Overview of the Electrocardiogram (ECG)
An Electrocardiogram, commonly called an ECG, is a quick and non-invasive test that records the electrical activity produced by the heart.
Unlike an echocardiogram, an ECG does not create an image of the heart.
Small adhesive electrodes are placed on the chest and limbs and connected to an ECG machine.
The resulting tracing provides information about heart rate, rhythm and the way electrical impulses travel through the heart.
A resting ECG can identify many arrhythmias, conduction abnormalities and characteristic electrical patterns.
It can also show changes that may be associated with heart strain, previous cardiac injury, electrolyte disturbance or the effects of certain medicines.
However, an ECG records only a relatively short period of heart activity.
Intermittent palpitations or arrhythmias may therefore occur when the recording is not being taken.
A normal resting ECG does not rule out all heart disease and does not directly assess the heart valves or pumping function.
The Electrocardiogram (ECG) is available as both a clinic visit and a home visit.
The test starts from £80.
What Does the Electrocardiogram (ECG) Assess?
The ECG provides a snapshot of the heart's electrical activity.
Heart rate
Records how fast the heart is beating during the test.
Heart rhythm
Assesses whether the heartbeat follows a normal sinus rhythm or another pattern.
Arrhythmias
Can identify rhythm abnormalities present during the recording.
PR interval
Provides information about electrical conduction between the atria and ventricles.
QRS complex
Assesses ventricular electrical activation.
QT interval
Measures ventricular electrical recovery and can be important with selected medicines or clinical conditions.
Electrical axis
Provides information about the overall direction of cardiac electrical activity.
Heart strain patterns
Selected ECG changes can occur with cardiac enlargement or pressure load.
Ischaemic or injury-related changes
Certain patterns can raise concern about reduced blood supply or myocardial injury.
Who May Benefit From the Electrocardiogram (ECG)?
People experiencing palpitations - An ECG can identify an arrhythmia if it is present during the recording.
People with an irregular pulse - The tracing can define the rhythm more accurately.
People with unexplained dizziness or fainting - Rhythm or conduction abnormalities are among the possible causes.
People with known heart disease - ECG can form part of ongoing cardiac monitoring.
People taking medicines that can affect cardiac conduction - ECG intervals can be monitored where clinically appropriate.
People with an abnormal cardiac examination - Electrical information can complement structural assessment.
People undergoing selected pre-operative or medical assessments - ECG is often used as a baseline investigation.
People requiring cardiac testing at home or in clinic - Both service options are available.
Symptoms and Reasons to Consider the Electrocardiogram (ECG)
Palpitations or a racing heartbeat - ECG can identify many abnormal rhythms when they are occurring.
An unusually slow heartbeat - Bradycardia can be documented.
Irregular heartbeat - Atrial fibrillation and other rhythm abnormalities can produce characteristic ECG patterns.
Dizziness or unexplained fainting - Electrical or rhythm disturbances are among the possible causes.
Shortness of breath with a cardiac concern - ECG can contribute to the wider assessment.
Chest discomfort under clinical investigation - ECG is an important cardiac test, although acute chest pain requires urgent assessment.
Monitoring after a previous abnormal ECG - Repeat tracing can allow comparison.
Monitoring medication effects - Selected drugs can alter heart rate, rhythm or QT interval.
Severe or persistent chest pain, sudden severe shortness of breath, collapse, new weakness on one side, or symptoms suggesting a heart attack require emergency medical care.
Do not wait for a private routine ECG when an acute cardiac emergency is possible.
How to Prepare for the Electrocardiogram (ECG)
Do not stop cardiac medication simply to obtain an ECG unless the prescribing clinician has specifically instructed you to do so.
What Happens During the Electrocardiogram (ECG)?
The standard resting ECG takes only a few minutes to record.
Is the Electrocardiogram (ECG) Safe?
A standard ECG is non-invasive.
It does not send electricity into the body; the electrodes only detect the electrical signals naturally produced by the heart.
There is no ionising radiation.
The test is painless, although removing adhesive electrodes can cause minor temporary skin discomfort.
How to Book Your Electrocardiogram (ECG)
The ECG can be arranged privately either at a London clinic or through an available home appointment.

Select your appointment type
Choose an in-clinic appointment or available home visit.
Provide your cardiac history
Include symptoms, medicines and previous heart conditions.
Attend or receive your appointment
A trained healthcare professional records the ECG.
Clinical interpretation
The tracing is reviewed for rate, rhythm and other electrical findings.
Receive your report securely
The authorised ECG report is provided following review.
When Will I Receive My Results?
The current London Blood Tests reporting turnaround is approximately 1 day.
The ECG tracing itself is produced immediately, but formal clinical interpretation and reporting may follow separately.
Urgent abnormalities or significant symptoms require prompt clinical assessment rather than routine follow-up.
Understanding Your Electrocardiogram (ECG) Results
A normal ECG commonly shows sinus rhythm with electrical intervals and patterns within expected limits.
Abnormal findings can include atrial fibrillation, tachycardia, bradycardia, conduction delay or other rhythm abnormalities.
Selected ECG patterns can also suggest previous or current cardiac injury, heart strain or electrolyte abnormalities.
However, an ECG must always be interpreted in context.
A normal resting ECG does not exclude intermittent arrhythmia, coronary artery disease or structural heart disease.
Longer ambulatory monitoring, echocardiography, blood tests or other cardiac investigations can sometimes be necessary.
What Can the Electrocardiogram (ECG) Detect?
Atrial fibrillation - An irregular rhythm can produce a characteristic ECG pattern.
Tachycardia - Abnormally fast rhythms can be documented.
Bradycardia - Abnormally slow heart rates can be identified.
Conduction abnormalities - Electrical delays and heart block patterns can be detected.
QT-interval abnormalities - Prolongation or shortening can be measured.
Selected heart-strain patterns - Electrical changes can occur with structural or pressure-related cardiac conditions.
Changes suggestive of myocardial injury - Certain ECG abnormalities can raise concern about heart damage and require urgent clinical correlation.
Limitations of the Electrocardiogram (ECG)
It records only a short period of heart activity - Intermittent arrhythmias can be missed.
It does not directly image the heart - Echocardiography is used for valves, chambers and pumping function.
A normal ECG does not rule out coronary artery disease - Other testing may be required.
An abnormal ECG does not automatically establish one diagnosis - Several conditions can produce similar patterns.
Ambulatory monitoring may be needed for episodic symptoms - A Holter or longer event monitor records the rhythm for a longer period.
