The heart is the most important organ, without the stable work of which the normal functioning of the entire human body is impossible. Thanks to him, every cell of our body, every organ is supplied with oxygen and nutrients carried by the blood. The heart works continuously, without the right to take breaks. It is because of this that it requires increased attention to itself, to its state. After all, life depends on the heart.
Thanks to the development of medical science and medical technology in particular, monitoring the work of the heart has become easier and more convenient. A device such as an electrocardiograph helps cardiologists in this. He "reads" the work of the organ, displaying the results on paper in the form of a zigzag line - a cardiogram, according to which doctors determine whether the work of the organ fits into the norm or requires support and treatment.

The electrocardiograph is an indispensable device in the work of ambulances, specialists at polyclinics, departments of cardiology, intensive care, etc. It is important to understand that an electrocardiorecorder is needed not only for patients with diseases of the cardiovascular system, but also for healthy people. Indeed, regular recording of cardiograms contributes to the earliest possible detection of failures and deviations, especially in people whose work is associated with high physical and psycho-emotional stress (athletes, military, firefighters, etc.).
An electrocardiograph is a medical device that records electrical impulses of the heart muscle when the heart is working.
Depending on how many leads (from 1 to 12) the device synchronously registers, single and multichannel cardiographs are allocated. This indicator characterizes the performance of the device. Single-channel and 12-channel machines both detect all 12 channels, but the difference is that the first one records sequentially on one channel, while the second records all simultaneously. In addition to the above, there are also three- and six-channel devices that simultaneously record 3 and 6 channels. The cost of the cardiorecorder depends on the channel, the more it is, the higher the price, respectively.
Single-channel devices are most often used when equipping ambulances. They are more compact, most often equipped with a rechargeable battery for autonomous operation. Also, they are characterized by a low cost, available to almost everyone. Of the shortcomings, limited functionality can be distinguished.
Three-channel, due to the simultaneous recording of 3 channels, have a higher performance than the first. Often they have the opportunity to enter additional data about the patient from whom the cardiogram is taken (gender, age). They have an internal memory, albeit small, for storing research results.
Six-channel devices are even more productive.Due to this, they are used in clinics, in cardiological ambulances. Features a more powerful battery, more memory, printing speed and functionality.
Twelve-channel are the most functional and productive devices. They simultaneously register the work of the heart in 12 leads and are used for a detailed and multivariate study of the work of the heart. They are characterized by a large amount of memory, a wide range of functions, interpretation of the received data, etc. They are distinguished by their high cost.
When choosing an electrocardiograph, you should pay attention to a number of criteria. Briefly about each of them:
The performance of the device depends on it, as mentioned above.
At that point, you should pay attention to the battery capacity, the larger it is, the longer the device can work autonomously.
It allows you to view test results before printing, which often helps save thermal paper. In a display, its size and resolution are important. The larger it is, the more useful information is placed on it. The touch screen will be an advantage.
It is necessary to view cardiograms of patients taken at different times. Most often, single-channel ones do not have built-in memory. For the rest, its volume allows recording from 10 to 500 EGK files. The advantage will be the presence of a slot for connecting external media.
The larger the paper used, the more data it can hold. The advantage will be the ability to use paper of different widths. The print speed is most often adjustable and ranges from 5 to 50 mm / s.
This function is necessary for data transfer and their further processing. To this end, the models are equipped with various USB, COM connectors, as well as BLUETOOTH and WLAN interfaces for wireless information transfer.
Allows you to identify abnormalities in the work of the heart and make a diagnosis.
These were the main criteria to look out for when choosing a cardiograph. Also, for a specialist cardiologist, such indicators as the accuracy and sensitivity of the device, as well as the reliability of the manufacturer, will be important.
This cardiograph is produced by the Chinese company Shenzhen Carewell Electronics Co. The device is Russified. Equipped with a 3.8 "backlit monochrome LCD screen, which during operation displays the current lead, patient's heart rate, operating characteristics (mode, sensitivity, filters, paper feed speed, battery level, etc.). The device automatically measures and interprets the ECG based on the CSE and AHA databases. The heart rate measurement range is from 30 to 215 beats per minute with an accuracy of 1 beat. The ECG results are displayed using a built-in thermal printer on thermal paper 50 mm wide, the recording width is 48 mm. The paper feed speed can be adjusted from 5 to 50 mm / s. The cardiograph operates both from a 220-240 V household network and from a built-in battery that can withstand up to 500 charging cycles. It takes 8 hours to fully charge the battery.
