An electrocardiogram — shortened as EKG or ECG — is a test that estimates the electrical movement of the heartbeat. With each beat, an electrical drive (or “wave”) goes through the heart. This wave makes the muscle press and siphon blood from the heart. A typical heartbeat on ECG will show the planning of the top and lower chambers.
An electrocardiogram (ECG) is a medical test that detects cardiac (heart) abnormalities by measuring the electrical activity generated by the heart as it contracts. The machine that records the patient’s ECG is called an electrocardiograph
When are ECGs needed
Usually, you do not need an ECG if you don’t have risk factors for heart disease or symptoms that suggest possible heart disease
In some cases, it can be important to get this test. You should probably have an ECG if you have risk factors for an enlarged heart such as high blood pressure or symptoms of heart disease, such as chest pain, shortness of breath, an irregular heartbeat or heavy heartbeats. You may need the test for screening or occupational requirements, or if you have a personal or family history of heart disease, diabetes or other risks and you want to start exercising.
