What is ECG?

Many modern tests have been developed to diagnose different types of heart disease. ECG is one of them.

Electrocardiography or  ECG  (English: Electrocardiography;) is a cardiovascular method in which the activity of the human heart is electronically determined and recorded with the help of a cardiograph. Cardiographs measure the electrical potential at the surface of the human body and for some time contain a continuous record of the electrical current associated with the activity of the heart muscle. Any abnormalities are determined by comparing the records obtained from the test heart with the normal heart. This record is available in the form of a graph.

The origin of the word electrocardiography  or  ECG is:

The word is derived from the Greek electro, meaning related to the electrical activity; Cordia, which means heart; And graph, which means "to write".

Why ECG?

If a patient needs to be examined, the cardiologist says to do this test first. This test does not require the patient to have a tear or something inserted into the body. The test is completed in just five minutes. Whether the heart is working at its normal rhythm, the position of the heart, whether any part of the hoops has become too thick, whether any part of the hoops has been damaged, ECG is an attempt to understand whether there is any abnormality in the blood flow by observing the electrical activity of the heart. 

The results of the ECG test are reported in the form of a graph on a piece of paper. In modern ECG machines, the ECG graph can be observed instantly on a display. By looking at this graph, the doctor understands whether the patient has had a heart attack or whether the regular rhythm of the heart is correct. To perform this test, the patient is laid on a flatbed and electrodes are placed at six designated places near the heart. 

The test is completely painless and does not require any preparation. ECG is performed not only in patients with chest pain and shortness of breath but also in older patients as part of the preparation for surgery. Apart from that, ECG is also a part of regular health examination. However, heart disease is not detected by ECG. In this case ETT
