ANATOMY

Detailed explanation-1: -Answer and Explanation: Electrocardiography (ECG or EKG) is the recording of electrical changes occurring in the myocardium during the cardiac cycle.

Detailed explanation-2: -Electrocardiograph can record electrical changes during heart beat. Electrocardiography is the process of recording the electrical activity of the heart over a period of time using electrodes placed on a patient’s body.

Detailed explanation-3: -During an ECG, up to 12 sensors (electrodes) are attached to the chest and limbs. The electrodes are sticky patches with wires that connect to a monitor. They record the electrical signals that make the heart beat. A computer records the information and displays it as waves on a monitor or on paper.

Detailed explanation-4: -ECG depicts the depolarisation and repolarisation process during the cardiac cycle. In the ECG of a normal healthy individual one of the following waves is not represented.

Detailed explanation-5: -An electrocardiogram (EKG, ECG) is a test that measures the electrical signals that control heart rhythm. The test measures how electrical impulses move through the heart muscle as it contracts and relaxes. The electrocardiogram translates the heart’s electrical activity into line tracings on paper.
