Several examples of the beneficial uses in diagnosis and treatment of cardiac patients are mentioned. However, keep in mind that the current list is only a brief summary and in real life the use of the ECG is broader. First, the ECG is an important tool in diagnosing and managing acute myocardial infarction. In patients with chest pain that is suspect for myocardial ischemia, the characteristic ST-segment changes (elevations or depressions) are one of the important corner stones of diagnosis and subsequent treatment.  In addition, rapid resolution of the ECG changes of myocardial infarction after reperfusion therapy has prognostic value and identifies patients with reperfused coronary arteries.

In the diagnosis of the cause for severe rhythm disturbances, cardiac shock or after cardiac arrest the ECG is also of great importance for rapidly assessing possible underlying (cardiac) causes. Metabolic disturbances or medication induced arrhythmias can induce characteristic changes of the QT time, QRS and ST morphology. The diagnosis based on the ECG observations can be life-saving in emergency situations with patients in shock or after a cardiac arrest.
