Electrocardiography - Wikipedia
Electrocardiography is the process of producing an electrocardiogram (ECG or EKG[a]), a recording of the heart's electrical activity through repeated cardiac cycles. [4] . It is an electrogram of the heart which is a graph of voltage versus time of the electrical activity of the heart [5] using electrodes placed on the skin.
Electrocardiogram (ECG or EKG) - Mayo Clinic
2024年4月2日 · An electrocardiogram (ECG or EKG) is a quick test to check the heartbeat. It records the electrical signals in the heart. Test results can help diagnose heart attacks and irregular heartbeats, called arrhythmias. ECG machines can be found in medical offices, hospitals, operating rooms and ambulances.
Electrocardiogram (ECG or EKG) | American Heart Association
2022年12月7日 · An electrocardiogram — abbreviated as EKG or ECG — measures the electrical activity of the heartbeat. With each beat, an electrical impulse (or “wave”) travels through the heart. This electrical wave causes the muscle to squeeze and pump blood from the heart. A normal heartbeat on ECG will show the rate and rhythm of the contractions in ...

An electrocardiogram (ECG) is a test that records the electrical activity of the heart. If your heart has been beating too fast, or you've been having chest pain, both you and your doctor will want to find out what's causing the problem so you can get it treated. One way to diagnose heart problems is with a test of the heart's electrical ...
