What is the purpose of an ECG?

The purpose of an ECG, or electrocardiogram, is to assess the electrical activity of the heart. This test captures the electrical impulses that trigger each heartbeat, providing valuable information about the heart’s rhythm, size of the chambers, and any issues with the electrical conduction pathways. By analyzing these electrical signals, healthcare providers can identify various cardiac conditions, such as arrhythmias, heart attacks, and other heart-related issues.

This is crucial for determining how well the heart is functioning and for guiding treatment decisions. The ECG is a non-invasive test that can be performed quickly and can offer immediate insights into the patient’s cardiac status, making it an essential tool in both emergency and routine medical settings.
