In patients with chest pain, the ECG is important but sometimes
misleading.
!It is essential to remember that the ECG can remain
normal for some hours after the onset of a myocardial infarction.
Too often patients are sent home from an A&E department because their
ECG is normal, despite a reasonably convincing story of ischaemic
chest pain. Under such circumstances the ECG should be repeated
several times to see if changes are appearing, and patient management
should depend on the plasma troponin level rather than on the ECG.
