Question

Q. Explain electrocardiogram??
​

Answer 1

Answer:

Electrocardiography is the process of producing an electrocardiogram. It is an electrogram of the heart which is a graph of voltage versus time of the electrical activity of the heart using electrodes placed on the skin.

Answer 2

• Many individuals have previously undergone an electrocardiogram, whether for regular checks or for cardiac diagnoses (ECG or EKG).
• But, what exactly does it measure, and what does the ECG curve reveal?
• Electrical and chemical impulses allow nerve and muscle cells to interact with one another.
• Our heartbeat is also regulated by electrical impulses.
• These signals are sent by the sinoatrial node (SA node), a collection of cells in the right atrium of the heart, and they travel through the heart muscle tissue as little electrical impulses.
• The heart's atria and ventricles contract first, followed by the atria.
• On the surface of our skin, we can monitor how these impulses travel through the heart.
• An ECG graphs these variations in electrical signals (or, more accurately, voltage) on various sections of skin. An ECG graph is created as a result of this process.
