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: -An electrocardiogram (ECG or EKG) records the electrical signal from the heart to check for different heart conditions. Electrodes are placed on the chest to record the heart’s electrical signals, which cause the heart to beat.

Detailed explanation-4: -A typical ECG tracing of the cardiac cycle (heartbeat) consists of a P wave (atrial depolarization ), a QRS complex (ventricular depolarization), and a T wave (ventricular repolarization). An additional wave, the U wave ( Purkinje repolarization), is often visible, but not always.

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.
