There are two commonly used tests to evaluate the health of the heart: the electrocardiogram (ECG/EKG) and the echocardiogram. The ECG test is performed by specialized technicians who monitor the heart's electrical activity. It involves placing adhesive electrodes on the body to record the heart's electrical signals, which are then displayed as wave patterns on paper. This painless and safe procedure is able to detect a wide range of cardiovascular issues. It can identify changes in heart wall thickness, an enlarged heart, irregular heartbeats, heart attacks, and damaged tissue.

If any abnormalities are detected during the ECG test, an echocardiogram may be ordered. This test uses ultrasound technology to create visual images of the heart. It is conducted by Ultrasound Technologists or Sonographers. By using sound waves, the echocardiogram can provide detailed information about the heart's structure and function. It can assess the size and shape of the heart, the movement of its valves, and the efficiency of its pumping action.

In recent years, advancements in technology have revolutionized ECG systems. PC-based ECG machines have replaced traditional paper printouts with electronic storage, making it easier to integrate the test results with medical records. Additionally, some ECG machines now offer spirometry, a lung function test, helping to provide a more comprehensive assessment of cardiovascular health.

Overall, the ECG and echocardiogram are valuable tools in diagnosing and monitoring heart conditions. They play a crucial role in assessing heart health and guiding appropriate treatment plans.
