ECG
An electrocardiogram (ECG) is a medical test that detects heart problems by measuring the
electrical activity generated by the heart as it contracts.
ECGs from healthy hearts have a characteristic shape. Any irregularity in the heart rhythm
or damage to the heart muscle can change the electrical activity of the heart so that the
shape of the ECG is changed.
A doctor may recommend an ECG for people who are displaying symptoms such as chest pain,
breathlessness, dizziness, fainting or fast or irregular heartbeats.
The ECG is a safe and non-invasive procedure with no known risks.
