How does the ECG machine interact with the heart's rhythm?

The ECG machine functions primarily as a monitoring device for the heart's electrical activity and rhythm. It does not have the capability to control, restore, or enhance the heart's rhythm or rate. Instead, it records the electrical impulses that initiate each heartbeat, thereby providing valuable information about the heart's functioning.

The ECG translates the heart's electrical signals into a visual representation on paper or a digital display, allowing healthcare professionals to assess the heart’s rhythm for any abnormalities, such as arrhythmias. Through this monitoring capability, clinicians can make informed decisions about diagnosing conditions or determining the severity of a heart problem, but the ECG itself does not intervene in the heart's activity or affect its rhythm.
