ECG; Syn. Actinocardiogram

ECG; Syn. Actinocardiogram: what is it and how do they work?

An ECG, or electrocardiogram, is one of the most common methods for diagnosing heart disease. It is a record of changes over time in the potential difference of the electric field (biopotentials) of the heart during its contractions. Syn. Actinocardiogram is an obsolete term that is sometimes used synonymously with ECG.

The ECG procedure does not require special preparation and is very simple. The patient has electrodes placed on his chest, arms and legs, which record the electrical activity of the heart. Then the data from the electrodes is transmitted to an ECG machine, which converts the data into a graphical form - a curve reflecting changes in the biopotentials of the heart.

The ECG waveform has a specific pattern that allows doctors to determine many aspects of heart health, such as the rhythm, rate, size of individual parts of the heart, and the presence of ischemia (insufficient blood supply to the heart). An ECG can also be used to monitor cardiac activity over an extended period of time, which can detect arrhythmias and other cardiac problems.

Syn. The actinocardiogram, which is also known as SAH, was developed in the USSR in 1935 and is one of the predecessors of the ECG. It is a recording using photographic film onto which electrical signals from the heart are projected. SAH is no longer used in modern medicine, as it has been replaced by more modern and accurate methods such as ECG.

Overall, an ECG is a safe and noninvasive method for diagnosing heart disease that allows doctors to determine many aspects of heart health. If you have any heart-related symptoms, contact your doctor for advice and, if necessary, an ECG.

ECG (Extrocardiac potentials) and Syn. Actin. Cardiogram/Actinocardiography

ECG is one of the most common methods for diagnosing cardiovascular diseases. It allows you to determine the electrical activity of the heart and evaluate its changes during its operation. Syn. actin. cardiogram/actinocardiography is a method for studying cardiac activity based on recording extracardiac potentials, that is, potentials arising outside the heart. The waves of the curve are most often recorded with an increase in blood filling of the atria, a characteristic drop in the waves of the curve during the cardiac cycle, characterized by the speed of recovery of the waves after excitation. Analysis of the electrical activity of the heart makes it possible to diagnose various diseases and disorders of the heart muscle. In this article we will look in more detail at the definition of ECG and Syn.Actin.Cardiograms/Actinocardiography.

ECG: ECG (Electrocardiography) is a method for studying the electrical activity of the heart. It is widely used in medical practice to determine the condition of the heart and diagnose heart diseases.
