As a medical professional with expertise in cardiology, I can explain that an ECG (Electrocardiogram) is a non-invasive test that records the electrical activity of the heart. It's a crucial diagnostic tool used to detect and monitor a variety of heart conditions.
Here's a step-by-step explanation of what an ECG does:
1. Placement of Electrodes: Small electrodes are placed on the patient's limbs and chest to pick up the electrical signals from the heart.
2. Recording the Heart's Rhythm: The ECG machine records the heart's rhythm, which is the pattern of its electrical impulses. These impulses cause the heart to contract and pump blood.
3. Identifying Heart Conditions: By analyzing the ECG tracing, doctors can identify conditions such as:
- Arrhythmias: Irregular heart rhythms.
- Myocardial Infarction (Heart Attack): Evidence of a heart attack can be seen as changes in the ECG waves.
- Hypertrophy: Enlargement of the heart muscle.
- Ischemia: Reduced blood supply to the heart.
- Long QT Syndrome: A heart rhythm disorder that can cause fast, chaotic beats.
4. Assessing Heart Health: An ECG can also be used to monitor the effects of medications or procedures on the heart.
The ECG is a quick, painless, and safe test that provides valuable information about the heart's function and is often the first test conducted when someone is experiencing symptoms like chest pain or shortness of breath.

An electrocardiogram (ECG) is a test which measures the electrical activity of your heart to show whether or not it is working normally. An ECG records the heart's rhythm and activity on a moving strip of paper or a line on a screen.
