An ECG test, or electrocardiogram, is a non-invasive diagnostic tool that records the electrical activity of the heart over a period of time. It is achieved by placing electrodes on the patient’s skin.

ECGs are crucial for detecting cardiac abnormalities, including arrhythmias, heart attacks, and other heart disorders. This test is particularly valuable in monitoring healthspan as it helps in early detection and management of heart conditions that could compromise both longevity and quality of life.
