- 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
An electrocardiogram (ECG or EKG) is a test to record the electrical signals in the heart It shows how the heart is beating Sticky patches called electrodes are placed on the chest and sometimes on the arms or legs Wires connect the patches to a computer, which prints or displays results
- Electrocardiogram (EKG) | American Heart Association
What is an electrocardiogram? An electrocardiogram measures the electrical activity of the heartbeat With each beat, an electrical wave travels through the heart This wave causes the muscle to squeeze and pump blood from the heart A normal heartbeat on an EKG will show the rate and rhythm of the contractions in the upper and lower chambers

It doesn’t take long and doesn’t cause pain, but an electrocardiogram can tell your healthcare provider if you’ve had a heart attack, heart failure or heart damage It can also tell them if your heart rhythm isn’t normal or how well your pacemaker is working An EKG shows the frequency and duration of your heartbeat What is an EKG?
- Electrocardiography | Definition Uses | Britannica
electrocardiography, method of graphic tracing (electrocardiogram; ECG or EKG) of the electric current generated by the heart muscle during a heartbeat The tracing is recorded with an electrocardiograph (actually a relatively simple string galvanometer), and it provides information on the condition and performance of the heart

What Is an Electrocardiogram? An electrocardiogram, also called an ECG or EKG, is a simple and painless test that measures the electrical impulses of your heart to check for signs of heart
- Electrocardiography - Heart and Blood Vessel Disorders - MSD Manual . . .
Electrocardiography (ECG) is a quick, simple, painless medical test that measures the heart’s electrical impulses During an ECG, the heart's electrical impulses are measured, amplified, and recorded
- Electrocardiography - Cardiovascular Disorders - MSD Manual . . .
The standard electrocardiogram (ECG) provides 12 different vector views of the heart’s electrical activity as reflected by electrical potential differences between positive and negative electrodes placed on the limbs and chest wall
