What do you need to know about electrocardiograms?
Everyone must stay at home to help stop the spread of coronavirus. An electrocardiogram (ECG) is a simple test that can be used to check your heart’s rhythm and electrical activity. Sensors attached to the skin are used to detect the electrical signals produced by your heart each time it beats.
What can an ECG tell you about your heart?
Among other things, an ECG can be used to measure the rate and rhythm of heartbeats, the size and position of the heart chambers, the presence of any damage to the heart’s muscle cells or conduction system, the effects of heart drugs, and the function of implanted pacemakers.
Is it painful to have an electrocardiogram done?
An ECG is a quick, safe and painless test. No electricity is put into your body while it’s carried out. There may be some slight discomfort when the electrodes are removed from your skin – similar to removing a sticking plaster – and some people may develop a mild rash where the electrodes were attached.
How many electrodes are used in an ECG?
Electrocardiography. In a conventional 12-lead ECG, ten electrodes are placed on the patient’s limbs and on the surface of the chest. The overall magnitude of the heart’s electrical potential is then measured from twelve different angles (“leads”) and is recorded over a period of time (usually ten seconds).

How is an ECG used to diagnose heart problems?
It can be used to investigate symptoms of a possible heart problem, such as chest pain, palpitations (suddenly noticeable heartbeats), dizziness and shortness of breath. An ECG can help detect: arrhythmias – where the heart beats too slowly, too quickly, or irregularly.
Is there a UK study on ECG accuracy?
A number of studies have previously identified inconsistency in reporting ECGs, among diverse groups of clinicians, but no recent study has addressed this in UK primary care. This study has examined the level of accuracy in ECG interpretation in primary care and cardiology in a large city.
What’s the difference between an EKG and an ECG?
Not to be confused with other types of electrography or with echocardiography. Electrocardiography is the process of producing an electrocardiogram ( ECG or EKG ), a recording – a graph of voltage versus time – of the electrical activity of the heart using electrodes placed on the skin.
