Long-term cardiac monitoring systems extend the diagnostic capabilities of stationary electrocardiographs and can monitor heart function over a protracted period. To date, there are many options for implementing long-term cardiac monitoring systems that differ from each other both structurally and functionally. However, all systems used on the market have a variety of disadvantages that do not allow combining the device with high quality readings and convenient operation at the same time. In this work, the developed wearable long-term cardiac monitoring system is presented that registers 12 standard electrocardiogram leads. Measurement of electrical potentials from the skin surface is carried out by a group of capacitive sensors connected by stretchable cables to the processing device, thereby excluding from the design long cables that cause discomfort to the patient during prolonged use. A possibility was shown to transmit ECG via USB cable, microSD card or device’s wireless Bluetooth pairing to a smartphone, and to record and transmit the patient’s position and movement data for comparison with the electrocardiogram using built-in MEMS sensor. The description of the design and operation of the functional units of the system is given. The developed system is characterized by low weight-size parameters that improves patient’s experience during long-term cardiac monitoring, while maintaining the diagnostic capabilities to detect various cardiovascular diseases.
