Overview

The key findings to look for on EKG is ST elevation which is characteristic of myocardial infarction. Diffuse ST elevation may point to the diagnosis of pericarditis. Serial EKG's should be obtain to evaluate for continued or progression of myocardial injury over time.

Electrocardiogram

  • An electrocardiogram is usually required for initial evaluation of chest pain.
  • It iis very useful for the diagnosis of several etiologies of chest pain such as;

Acute coronary syndrome

  • A standard 12 lead ECG is recommended in all patients with chest pain within 10 minutes of presentation if acute coronary syndrome is suspected[1][2].
  • Findings on ECG suggestive of ACS include[3][4], ST elevation, ST depression and a new left bundle branch block (LBBB)
  • It is important to note that a normal ECG does not rule out the presence of an acute myocardial infarction as ECG can show a hyper-acute T wave[5][6] [7] as an early presentation.
  • If an initial ECG is non-diagnostic and there is still a high clinical suspicion of an MI, a repeat ECG should be conducted.
  • It is helpful to have precious ECGs of a patient to determine if findings observed are new.

Shown below is an EKG demonstrating clear ST elevation in the right precordial leads depicting STEMI. A coronary angiography revealed a proximal right coronary artery occlusion[8].

Pericarditis

  • ECG findings in patients with pericarditis may mirror that seen in acute myocardial infarction and carrying changes may be seen as the disease progresses.
  • Findings on ECG suggestive of pericarditis at different levels include[9],
  • Stage I: ST elevation in all leads; PTa depression (depression between the end of the P wave and the beginning of the QRS complex)
  • Stage II: Pseudonormalization (transition)
  • Stage III: Inverted T waves
  • Stage IV: Normalization
