Cardiography

The diagnostic direction of the heart describes complex medical techniques that involve visualization and assessment of the functioning of internal organs using a device that records the periodicity of the heart rhythm. This area is closely related to specialized medical practice, since in order to conduct a high-quality cardiological appointment, the doctor must be able to evaluate a number of indicators. Modern methods of carrying out the procedure are aimed at fixing the condition of the muscular organ, as well as improving the quality of diagnostic criteria in cardiology, which inevitably leads to minimizing medical errors in the field of cardiac diagnostics. It is these devices used in the diagnosis of cardiac diseases that the article cardiography talks about.

The classification of modern cardiography is carried out according to several key indicators: 1. Technology. Cardiograms are subject to requirements related to obtaining a high-quality image of cardiac phases: noise from extraneous factors is minimized, and amplification makes it possible to obtain a contrast image, the elements of which are clearly visible on photographic material. 2. Method of processing the results. To conduct the research, classical visual study or automatic data comparison can be used. The advantage of the latter method is the ability to obtain clear data on heartbeats, transmit the picture to a child, a person who does not fully understand medical terminology, or elderly patients, focusing on important elements. 3. Properties of the results obtained. A major role in determining the parameters of electrical activity is played by the patient’s condition at the time of the procedure (if a convulsion was caused, if the person is dealing with disorders of the coronary circulation of the myocardium). 4. Principle of use. There is an invasive method and a non-invasive technique, which uses different methods of collecting information, which is reflected in the patient’s behavior.

Introduction

Cardiography is a science that studies the functioning of the heart and cardiovascular system as a whole. It is an important part of medical diagnostics and is used to identify diseases of the heart and blood vessels, assess the patient's condition before surgery, and also to monitor treatment and the course of the disease. In this article we will look at the main methods of cardio

Cardiometry is a kind of diagnostic form that is widely used in medicine to obtain information about the cardiovascular system of a patient by measuring the electrical potentials of the heart. This includes the use of electrocardiography (ECG), pressure transducers, and other techniques to evaluate blood circulation, heart rhythm, and the electrical activity of the heart. In addition to physical cardiometry, there are also invasive and non-invasive cardiometry. This article focuses on invasive cardiometry. In this method, the patient will be given some kind of injection of some substance such as a liquid or conductive gel, which helps the electrical current to pass through the patient's body. Typically, the patient will have the material injected into the patient's veins, such as the cubital veins. Electrical signals will then pass through an electrode placed on their arm, reflecting the electrical activity of the patient's brain during diagnosis or treatment. Electrode patches are attached to the patient's skin in the areas where data needs to be recorded. Many medical devices can record, visualize and transmit data. Electrodes are inserted into the arms and legs.

Measuring such indicators as the travel time of sound waves from the transmitter to the device, the speed of propagation of these waves and other indicators can give an idea of ​​​​the condition of some organs, as they reflect fluctuations in the density/stiffness of the patient’s body. For example, echocardiography, cardiac ultrasound, EEG and many other medical devices use these methods to determine certain diagnoses.

Thus, cardiography allows you to obtain information about the work of the heart and its mechanical properties in real time. When interpreting cardiometric results, the doctor receives important information about various factors that help him make an accurate diagnosis and prescribe effective treatment or prevention if necessary.
