Electrocardiography ECG 12 Channel

An electrocardiograph (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. Some personal devices, such as smartwatches, can do simple ECGs. Ask your healthcare professional if this is an option for you.

Electrocardiograph

An electrocardiograph (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.

If you have a family history of heart disease, you may need an electrocardiogram to screen for heart disease, even if you don't have symptoms. The American Heart Association says ECG screening may be considered for those at low risk of heart disease in general, even if there are no symptoms. Most heart doctors consider an ECG as a basic tool to screen for heart disease, although its use needs to be individualized.

If symptoms tend to come and go, a regular ECG may not find a change in the heartbeat. Your healthcare team may suggest wearing an ECG monitor at home. There are several types of portable ECGs.
