The ECG (electrocardiogram) is a widely used test that records the heart’s electrical activity. The ECG provides important information about the heart’s rhythm, and it can also help diagnose other heart problems.
The heartbeat is regulated by electrical impulses that tell the heart muscle cells when to contract. The way in which these electrical impulses spread through the heart muscle determines the way in which the heart muscle contracts. This is known as the heart rhythm. As electrical impulses spread through the heart, the accompanying changes in electrical voltage can be measured by electrodes attached to the skin – the electrocardiogram.
