An ECG is often used alongside other tests to help diagnose and monitor conditions affecting the heart.

It can be used to investigate symptoms of a possible heart problem, such as chest pain, suddenly noticeable heartbeats (palpitations), dizziness and shortness of breath.

AnECG can help detect:

  • arrhythmiaswhere the heart beatstoo slowly, too quickly, or irregularly
  • coronary heart diseasewhere the heart's blood supply is blocked or interrupted by a build-up of fatty substances
  • heart attacks where the supply of blood to the heart is suddenly blocked
  • cardiomyopathywhere the heart walls become thickened or enlarged

A series of ECGs can also be taken over time to monitor a person already diagnosed with a heart condition or taking medication known to potentially affect the heart.
