OVERVIEW: ECG Dongle - inexpensive and very accurate pocket cardiograph

ECG Dongle - development of "Nordavind", which is engaged in a compound of the currently available technology and medicine. Kardiofleshka to make available this kind of survey as electrocardiography.

True if one considers that, according to RosstatIn Russia more than 23% of the population suffers from diseases of the circulatory system. This group includes just those diseases for which diagnosis and do an electrocardiogram.

Electrocardiography - is a diagnostic method based on measuring the electrical potential difference resulting from the work of the heart. The signals are recorded as a curve with a periodically repeated teeth. According to the location and shape of the teeth and the length of the intervals between them is estimated condition of the heart and its various tissues.

We understand how the ECG Dongle, and verified its accuracy.

Components and Operation

ECG Dongle is a USB flash drive, to which on the one hand joins the set of electrodes, and on the other - by means of an adapter - Android-smartphone. iOS users, unfortunately, try the device can not.

To record a reading operation hearts, You need to apply electrodes, as described in the instructions and install the application. The device makes the cardiogram with the six leads (for modern diagnostics is the required minimum). The default recording mode is carried out in 25 mm, but can be changed. The results are saved to PDF.

Simple user unfamiliar with a functional diagnosis, available several conclusions: the heart rate (pulse of that is) and the level of stress. It is unknown whether this is included in the heart rate.

The more you do not do anything, if you're not a doctor. To decrypt the ECG should be sent to "KardioOblako». This is a paid service, which will cost about 400 rubles. But the file can be sent, and your doctor for further evaluation and work.

An important point: ECG Dongle is not a medical device. I think this is due to the fact that the certification procedure for medical device is extremely complicated, lengthy and expensive. And it is unlikely it will pass the device, part of which is a smartphone based on Android. Well, the purpose and function in kardiofleshki entirely medical.

About the same - sticky electrodes on the chest and a compact box - shoot cardiogram Holter method. ECG Dongle, in fact, mixes and conventional Holter monitoring ECG measurements are carried out when the patient needs, not when he was appointed a visit to the doctor. But wearing the sensor does not need a whole day: the state of the heart is fixed within a short period of time.

dignity

The first thing that pleases - it's accuracy. We checked the work of ECG Dongle, comparing the readings and medical cardiograph under the control of functional diagnostics specialists.

ECG Dongle removes cardiogram correctly read her specialist is not difficult, reading the cardiograph and the stick did not differ.

The second big advantage - cost. This is a cheap version of Pocket ECG, it costs 3500 rubles. For such money it is impossible to imagine a medical device.

The third advantage - the ability to collect data in virtually any place where you can at least sit down. Heart performance depends on many factors. Even if you do an ECG, then smoked a cigarette, and then repeat the study, the results will be different. And with the memory stick it is possible to conduct a survey and after exercise, and stressAnd at rest. And all this without running around the clinic. For people who have problems with the heart, it is paramount, because it helps to collect the full picture of what happens to the body.

disadvantages

The main drawback - insufficient information. Modern cardiographs instantly appreciate not only heart rate but also the rhythm and ECG features and may even make a preliminary diagnosis. Frankly, this diagnosis, doctors often deny to decipher, but at the moment the user kardiofleshki and no such data.

It should make a reservation if you are not a doctor, to decipher an electrocardiogram - the last thing. You can even peruse a pile of books, and nothing will.

All doctors are taught to decipher an electrocardiogram, but in practice, the doctors themselves are turning to those who It specializes in functional diagnostics: very much nuances that become visible only with experience.

The second drawback - the high probability of a technical error. If you have come unstuck or just loosely fitted electrode when shakes the hand that holds the smartphone, so even if you're in the survey put the smartphone on his chest, then there is noise (so-called artifacts). This interference is converted into a cardiogram something indigestible. And they can appear not only at the beginning of the study.

For comparison: on the left - the same thing, right - readable indications, but artifacts are not always so obvious. Sometimes some noise spoil the whole picture.

I would like a more detailed explanation in the manual, what is considered correct overlay as a hedge against errors. For example, the device may interfere with oily skin or excessive hair growth on the chest.

results

ECG Dongle - is, without exaggeration, a cool device that really need it for the money. A little more work on the instruction - and kardiofleshka will only get better.

But everything about complex medical research (and electrocardiography - it's difficult), requires commitment from the patient. Otherwise, self-diagnostics and the subsequent self-will end in failure.

Therefore, you need to buy if:

1. I have heart problems, especially if you are trying to train and lead active lifestyle.
2. You have high physical and emotional stress.
3. You just will not boil the pot, evaluating the testimony without the help of a doctor.

With the last condition for the flash drive will bring only good and nothing but good.
