About ECG Testing

about-ecg-testingECG stands for Electrocardiography and is a cardiological process where the electrical activity of the heart is recorded over a given period of time using electrodes. These electrodes are used to detect tiny electrical changes in the depolarization pattern in the heart. ECG is a common performed and used cardiology test.

The most standard ECG is a 12 lead test where 10 electrodes are placed on limbs and chest and then the electrical patterns and potential are recorded from 12 angles. The test is about 10 seconds in duration. The overall magnitude of the depolarization is captured throughout the cardiac cycle. The short but powerful test creates a voltage vs time graph and the process is non-invasive.

There are many reasons that this is prescribed:

The most common reason for an ECG is to check the heart’s electrical activity. The test can also help find the source of unexplained chest pain/pressure as a result of heart attacks, or inflammation. Find the cause and explanation of heart disease including shortness of breath, dizziness, fainting and irregular palpitations. The ECG can also help determine if the heart chamber walls are too thick or thin. The ECG also monitors the implications and effects of medicine. The ECG is also commonly used to check and monitor devices such as pacemakers and related heart machines. Finally, the ECG commonly helps monitor heart health when other conditions are present.

ECGs are low risk, non invasive, safe and present little risk to users. The tests are common in countries across the world and present major benefits. The tests are relatively new and yet provide profoundly accurate readings in monitoring and in the discovery of heart conditions. For more information, speak to your health care provider about this. This is a test that can be performed within the physician’s office in most cases.
