Electrocardiogram (Ecg)

Electrocardiogram (ECG)

An electrocardiogram (ECG) is a graphic recording of the electrical potentials that accompany the work of the heart on a moving paper tape. An electrocardiogram is recorded using a special device called an electrocardiograph. An electrocardiograph records the electrical activity of the heart using electrodes placed on the skin at specific points on the body.

The resulting record is a graph reflecting the change in electrical potentials at various points in the cardiac cycle. The electrocardiogram clearly shows the P, Q, R, S, T waves, reflecting the processes of excitation of the atria and ventricles.

Analysis of the electrocardiogram allows you to evaluate the rhythm and frequency of heart contractions, identify conduction disturbances and other abnormalities in the functioning of the heart. Using an ECG, a doctor can diagnose various heart diseases, such as myocardial ischemia, heart attack, arrhythmias, etc. Characteristic changes in the ECG make it possible to determine the type of pathology and prescribe appropriate treatment.

An electrocardiogram is a graphical recording of the electrical potentials associated with the heart. It is performed using an electrocardiograph and allows the doctor to determine the presence of various heart diseases.

An electrocardiogram is recorded on a moving paper tape, where each peak and valley corresponds to a change in electrical potential in the heart. The doctor can analyze these changes and determine the presence of arrhythmia, coronary heart disease, myocardial infarction and other diseases.

When performing an electrocardiogram, your doctor may use special tests, such as a stress test or a bicycle ergometer, to look for heart problems that may be caused by exercise.

Overall, an electrocardiogram is an important tool in diagnosing heart disease and helps doctors determine the need for further testing and treatment.

Introduction: Diagnosis of heart disease using ECG

An electrocardiogram is a medical method that is used to evaluate the functioning of the heart and diagnose various cardiac pathologies. In this article we will look at what an ECG is, how it is performed and what diseases can be detected using this research method.

What is an electrocardiogram?

An ECG is a graphical representation of temporary changes in potentials in the heart rhythm on a paper tape or computer display. Electrocardiograms are recorded using special equipment - an electrocardiograph, which measures the heart's potential using several electrodes, usually placed on the patient's arms, legs and chest. The data obtained is converted into graphical forms on a piece of paper or on a computer screen, allowing doctors to analyze various parameters of the heart muscle.

What parameters can an ECG measure:

Amplitude. Occurs when the electrical activity of the heart changes during the cardiac cycle (the normal cycle of contraction and relaxation of the heart). When performing an ECG, it is necessary to take into account only the amplitudes of the P-waves and T-waves. R-R interval. Allows you to determine the period between two P waves. This parameter is measured as the distance between the earliest and the latest P wave in one cardiac cycle. It is also called the R-R interval. The shorter the R-R interval
