Electrocardiogram (ECG) is a test which records the electrical activities during contraction and relaxation of the heart to detect any heart-related abnormalities. These recordings are done with the help of a machine called an electrocardiograph.
Why is it relevant?
ECG of a healthy heart produces a characteristic shape. The damage to heart muscles or change in the heart rhythm impacts the heart’s electrical activities, leading to a change in the ECG shapes. These changes in the shape can be used to interpret underlying heart diseases and their risk. Hence, ECG is an important test commonly suggested in preventive healthcare.
Different types of ECG can be beneficial tools for measuring heart activities under different conditions:
ECG test is advised to find any limitations in the functioning of the heart. It has become an essential tool for healthcare professionals to prevent heart attacks by evaluating heart conditions at early stages. It is performed due to symptoms related to heart disease, including pain in the chest, dizziness, palpitations, shortness of breath, and weakness. ECG can also help to find out:
It is a noninvasive test in which you are asked to lie down. The small patches known as electrodes are attached to the arms, legs and chest. These patches are connected to an electrocardiograph. The electric signals originating from the heart are recorded. It can be used as a preventive test to help diagnose heart problems early and prevent severe complications like a heart attack. These preventive tests are especially beneficial for patients with chronic diseases.
A heart rate of 60-100 beats per minute is considered normal. Also, if the heart rhythm is even and consistent, it is considered normal.
In simple words, ECG can detect heart disease and associated risks. If you have a family history of cardiac complications or display symptoms like chest pain, dizziness, irregular heartbeats, or fainting, your doctor will advise ECG to know your health.
