Electrocardiography (Electrocardiography)

Electrocardiography is a method of recording electrical potentials accompanying the work of the heart. Electrodes are attached to a special recording apparatus (electrocardiograph), the other end of which is attached to the patient’s limbs or placed on his chest; The actual recording of electrical potentials accompanying the work of the heart is called an electrocardiogram (ECG). In traditional scalar electrocardiography, the electrocardiogram is usually recorded from lead 12, but in some cases it may be necessary to record the electrocardiogram using additional leads (for example, using an esophageal lead or an electrode located on the throat, as this helps to better diagnose the presence of arrhythmias). Vectorcardiography is a less common type of electrocardiography, but can also be performed to obtain a spatial picture of the electrical activity of the heart.

ELECTROCARDIOPHONOGRAPHY (electrocardiophonography) is a method of recording sounds and noises created during the work of the heart, simultaneously with an ECG. The sounds created during the heart's work pass through a microphone placed on the patient's chest, above the heart area. The resulting recording is called a phonocardiogram. This method allows for continuous recording of heart sounds and murmurs as it operates and is very useful in diagnosing various heart diseases.

Electrocardiography is a method of recording the electrical potentials of the heart, which allows you to evaluate its performance and identify possible disorders. This method is widely used in medicine to diagnose various heart diseases, such as arrhythmia, myocardial infarction, coronary heart disease, etc.

To conduct electrocardiography, special devices are used - electrocardiographs. They have several electrodes that are attached to the patient's skin and record the electrical potentials of the heart. The recording of electrical potentials is called an electrocardiogram.

Traditional electrocardiography usually records 12 channels, but in some cases additional channels may be required for a more accurate diagnosis. For example, an esophageal lead or an electrode placed on the throat may help better diagnose arrhythmia.

Vectorcardiography is a less common electrocardiography method. It provides a spatial picture of the electrical activity of the heart and can be useful in diagnosing arrhythmias.

There is also electrocardiophonography - a method of recording the sounds created by the heart during operation. This method is used to diagnose heart rhythm disorders and evaluate the functioning of the heart valves.

Thus, electrocardiography is an important method for diagnosing heart diseases and allows identifying disturbances in its functioning at an early stage.

Electrocardiography is a method of studying the heart using electrical signals that are recorded by special devices - electrocardiographs. This method is widely used in medicine for diagnosing cardiovascular diseases, assessing the effectiveness of treatment and monitoring the patient's condition during treatment.

In electrocardiography, electrodes are attached to the patient's limbs or chest, and the electrical activity of the heart is then recorded. Electrodes can be placed at different points of the body to obtain information about the functioning of different parts of the heart.

There are several types of electrocardiography: traditional (scalar) electrocardiography, vectorcardiography and electrocardiophonography. Vectorcardiography allows you to obtain a spatial picture of the electrical activity of the heart, and electrocardiophonography provides sounds and noises that may indicate the presence of pathology.

Electrocardiography is an important method for diagnosing the cardiovascular system and is widely used in medical practice. It allows you to detect heart rhythm disturbances, coronary heart disease, myocardial infarction and other heart diseases.
