Physiobelt: wireless ECG recording and analysis system for animals
The Physiobelt system is designed for long-term recording and transmission of an ECG signal with 500 Hz frequency via the radio channel and is used as part of a computer system that provides wireless reception of data and their processing in ECG researches of animals of the average and medium size (rabbits, guinea pigs, rats).
Key features and benefits of the system:
- 10 hours from a fully charged battery,
more than 100 days in standby mode - Transmission range - 10 meters
- Weight not more than 50 grams
The kit includes:
- Wireless amplifier Physiobelt
- The set of electrodes
- Radio module with USB interface
- Application software
- Vest for the animal
Areas of use:
- Testing of pharmaceuticals
- Training of students in courses of human and animal physiology
- Long-term monitoring of physiological parameters
- Veterinary Medicine
New features of the system:
- It is as easy as possible to work with system because on the body of the amplifier there are no buttons more
- The amplifier can be recharged by wireless charging (a wireless charger is purchased separately), the amplifier recharges via a USB cable
- The amplifier allows you to use more channels of registration (optional)
- Ability to change the sampling frequency, reducing the number of used channels: thus it is possible to register up to 8 channels with a frequency of 120 Hz and one channel with a maximum frequency of 946 Hz, also, there are intermediate values of frequencies for each selected number of leads
- The software allows to analyze heart rate (R-R intervals) of the animal in real time and keep the values of R-R intervals in textual or tabular (Excel) file

General questions
How to test the sensor without a rat?
Possible causes and what to do if there are no clear intervals or there are no other indications?
Possible reasons:
1) The electrodes are not in contact with the skin surface
Shave the contact areas and add electrode gel
2) The electrodes are in contact with each other
Too much gel added
3) Device Malfunction
Check on your hands by holding the contacts with the thumb and forefinger of your left and right hands, fingers should be moistened with gel (you can select the "Human" template at the bottom of the screen and your heart rate will be displayed)
