Cardiotachography

Cardiotachography is a method of studying the heart that allows you to determine its functional state and identify possible disorders. This method is based on measuring heart rate and blood pressure over a period of time.

To carry out cardiotachography, a special device is used - a cardiotachograph, which records an electrocardiogram (ECG) and blood pressure. The data obtained is then analyzed by a cardiologist.

Cardiotachography can be used to diagnose various heart diseases, such as coronary heart disease, arrhythmias, hypertension and others. This method can also help in assessing the functional state of the heart in healthy people.

It is important to note that cardiotachography is a safe research method that does not require special preparation of the patient. However, before conducting the study, it is necessary to consult a doctor to exclude possible contraindications.

**Cardiotachogram** (or ECG for short) is perhaps the most famous method of monitoring cardiac activity in the world, which has become an indispensable method for diagnosing and monitoring heart rate during physical activity.

The history of the ECG began in 1903 with the discovery of the electrocardiograph by Edward Leeds of the United States of America. During experiments to study the effects of exercise and drugs on a patient's cardiovascular system, his collaborator Thomas Addison turned to Leeds for help in creating a device capable of recording the electrical potentials of the human heart. Edward Leeds created an electrograph - an analogue of modern electrocardiographs and began the first experiment in transmitting a cardiogram in real time. Leeds, relying on the techniques, used a device he had previously developed to determine the movement of the tip of a pen on paper, now it was used to record changes in the electrical signals of the heart. This was the first time a cardiogram (ECG) was obtained that was not connected to other organs of the human body. Moreover, the design developed by Edward served as a kind of model for the installation of modern electrodes. With the development of medical electronics and the availability of equipment for mass production, ECG recording hardware has become a widely available means of heart treatment. Today one can notice clear progress in the creation of electronic devices designed for systematic medical monitoring.
