What is an essential step in the management of suspected ACS?

In the management of suspected acute coronary syndrome (ACS), obtaining a 12-lead ECG is a fundamental step. This diagnostic tool is crucial because it provides vital information about the heart's electrical activity and can help identify the presence, type, and extent of ischemia or infarction. The 12-lead ECG allows healthcare providers to detect ST-segment elevations or depressions, which are significant indicators of ACS. Early recognition through this method can ensure prompt treatment, which may include reperfusion therapy.

It is essential to establish the nature of the cardiac event quickly, as the treatment approach can vary depending on the findings from the ECG. This step takes priority to guide further care, such as medication administration or advanced interventions.
