What is the purpose of an EKG (electrocardiogram)?

The purpose of an EKG (electrocardiogram) is to assess the electrical activity of the heart. This test provides vital information about the heart's rhythm and its electrical impulses, allowing healthcare providers to detect a range of cardiac conditions such as arrhythmias, heart attacks, and other heart-related issues. The EKG captures the electrical signals that coordinate the heartbeats, giving insights into how well the heart is functioning.

By monitoring the electrical activity, medical professionals can evaluate how well the heart is pumping blood and identify any abnormalities in heart function. This information is crucial for diagnosing specific heart disorders and making informed decisions regarding treatment and management. Thus, an EKG is an essential tool in cardiology that focuses specifically on the heart's electrical dynamics, distinguishing it from tests that measure blood pressure, assess blood oxygen levels, or determine cholesterol levels.
