Electrocardiogram (ECG)

An electrocardiogram (ECG or EKG) is a medical test that records the electrical activity of the heart over a period of time. It involves placing small electrodes on the skin, which detect and measure the heart's electrical signals. The resulting graph shows the heart's rhythm, rate, and overall health. Doctors use ECGs to identify irregularities such as arrhythmias, heart attacks, and other heart-related conditions. This non-invasive test is quick and painless, providing valuable insights into how well the heart is functioning.
