Verified step by step guidance

Begin by understanding what an ECG (Electrocardiogram) is: it is a test that records the electrical activity of the heart over a period of time using electrodes placed on the skin.

Recognize that the primary function of an ECG is to monitor the heart's rhythm and electrical activity, which can help identify various heart conditions.

Consider the options given: lung infections, kidney stones, liver function abnormalities, and heart arrhythmias. Reflect on which of these conditions are related to the heart's electrical activity.

Understand that heart arrhythmias are irregularities in the heart's rhythm, which can be detected by observing the patterns in the ECG tracings.

Conclude that the ECG is specifically designed to detect heart arrhythmias, as it provides a visual representation of the heart's electrical activity, allowing healthcare professionals to identify any irregularities in the heart's rhythm.
