What is the primary function of an electrocardiogram (EKG/ECG)?

The primary function of an electrocardiogram (EKG/ECG) is to measure the electrical activity of the heart. This involves recording the electrical impulses that trigger each heartbeat. The ECG provides critical information about the heart's rhythm, the size and location of heart chambers, and any potential damage to the heart muscle. By analyzing the timing and strength of these electrical signals, healthcare providers can identify various cardiac conditions, such as arrhythmias, heart attacks, and other heart diseases. This makes the ECG a vital tool in both diagnosing and monitoring heart health. It captures real-time data that can guide treatment options and patient management effectively.
