2. **Process of ECG**: The process of obtaining an ECG is called electrocardiography. During this process, electrodes are placed on the skin to detect the electrical signals produced by the heart.

3. **Purpose of ECG**: The primary purpose of an ECG is to assess the heart's function. It helps in identifying various heart conditions, including arrhythmias (irregular heartbeats), heart attacks, and other cardiac diseases.

4. **Interpreting ECG Results**: The output of an ECG is a graph that shows the heart's electrical activity, including phases like systole (contraction) and diastole (relaxation). This graph helps doctors evaluate the heart's health and detect any abnormalities.

5. **Clinical Applications**: ECG is used in various treatments and diagnoses related to heart health. It is crucial for monitoring heart conditions, guiding treatment decisions, and assessing the effectiveness of ongoing treatments.

### Final Answer:
