Detailed explanation-1: -An electrocardiogram records the electrical signals in the heart. It’s a common and painless test used to quickly detect heart problems and monitor the heart’s health. An electrocardiogram-also called ECG or EKG-is often done in a health care provider’s office, a clinic or a hospital room.

Detailed explanation-2: -People often wonder why electrocardiogram is abbreviated as EKG instead of ECG. The reason is that ECG sounds very similar to EEG, which is the abbreviation for electroencephalogram, a test that measures electrical activity in the brain.

Detailed explanation-3: -An electrocardiogram (ECG) is a simple test that can be used to check your heart’s rhythm and electrical activity. Sensors attached to the skin are used to detect the electrical signals produced by your heart each time it beats.

Detailed explanation-4: -If the test is normal, it should show that your heart is beating at an even rate of 60 to 100 beats per minute. Many different heart conditions can show up on an ECG, including a fast, slow, or abnormal heart rhythm, a heart defect, coronary artery disease, heart valve disease, or an enlarged heart.
