Decoding the cardiogram is the most reliable method of diagnosis

The cardiogram is printed with a special device on film or paper. The graph shows the activity of the heart. All heart diseases are diagnosed with a cardiogram. With its help, one can observe the work of the circulatory system, the regularity and frequency of the heart rhythm, identify the slowing and blockade of blood conductivity, find out whether any of the cardiac tissues is susceptible to oxygen starvation, and also to determine previously transferred aneurysms and infarctions.

In addition, the decoding of the cardiogram makes it possible to determine the rate of contraction of the heart (pulse). The norm of the healthy heart of an adult person is at rest 60-80 beats per minute. Thanks to this it becomes possible to identify such phenomena as flicker and flutter. At flicker, the pulse can reach 600 beats per minute, and with flutter - 400.

The principle of the ECG is that the cardiograph registers the electric voltage lines that pass from the heart throughout the body. The parameters of these waves characterize the state of the heart. Like any vibrations, cardiovascular waves have amplitude and magnitude, and the decoding of the cardiogram reduces to the fact that according to these parameters the periodicity and strength of relaxation and tension of the heart muscles are calculated. According to these data, the patient is diagnosed. The cardiogram of the heart has peaks when a particular muscle is stressed, and the minimum amplitude is when it is relaxed.

On the ECG it is customary to put the notation in the form of Latin letters, due to this the decoding of the cardiogram becomes more accessible and simple. Consider the values assigned to these letters.

P - determines the state of the atria.

PQ is the interval showing the moment when both atria are strained.

QRS - these abbreviations denote a fragment of the electrocardiogram, which shows the work of the ventricles of the heart.

Q - determines the level of activity of the upper lobe of the heart.

R - shows the activity of the external part of the ventricles and the lower part of the heart.

ST - one of the main indicators on the electrocardiogram. It reveals the activity of both ventricles of the heart. Specialists pay special attention to the indicator T, which shows that the cells of the muscle tissue of the heart are in a normal state. It is on this characteristic of the ECG that diagnostics occur.

The gap between P and Q is the time interval for the transmission of activity (that is, energy, force) from the atrium to the ventricle. In a healthy heart, it should be 0.12-0.1 seconds. And the QRS peaks should pass for a time interval of 0.06-0.1 seconds. This indicator also builds a cardiodiagnostic.

Above we considered only the most basic characteristics that a cardiogram of the heart has. Deciphering by her specialists implies the use of more specific and deeper parameters (separately for each muscle, valve and vessel of the heart). This allows you to make a more accurate diagnosis of the disease.

It should be remembered that the final decoding of the cardiogram should be performed exclusively by a specialist. Possessing any knowledge in the field of medicine, but without being a doctor, you can see on the ECG only a superficial picture of the work of the heart. To put the final diagnosis and prescribe the treatment can only a cardiologist!
