NOMED-AF Project

The NOMED-AF project is carried out in the framework of strategic programme of research and development called “Prevention and treatment of modern age diseases” - STRATEGMED, 2nd tender. The aim of the project is to develop a system allowing to detect silent atrial fibrillation (Atrial Fibrillation, AF) in its early phase in the 65+ group of patients. The project will provide data on frequency of occurrence of the disorder that will become the basis to develop new treatment methods.

Silent atrial fibrillation is one of the most common types of heart rhythm disorders, which increases the stroke risk of 5-fold. The research indicates that there is a strong relationship between the prevalence of AF and age: the most vulnerable people are the elderly.

Elements Of The Solution

A vest for an ECG test

  • An innovative solution that allows to register a signal for 30 days

  • Wearing comfort (lightweight, tailored to the body)

  • Biocompatible materials

  • Special textile electrodes, which do not cause skin irritation, thanks to which a very good recording quality is obtained

NOMED-AF Sensor recorder for the vest

  • Operating time of battery power over 24h

  • Self-operating

  • Without connecting cables

  • Small in size

  • Minimum weight

NOMED-AF Dock transmission station

  • A transmission station that communicates data from the NOMED-AF Sensor recorder to the Remote Care Centre

  • A wide range of communication possibilities form the Monitoring Centre (3G, Wi-Fi, LAN)

  • Self-operating

Wrist watch ECG and pulse wave recorder – AF-Watch

The recorder enables automated detection of atrial fibrillations basing on a long-term monitoring, including in particular:

  • accurate detection of the episodes of latent atrial fibrillation (AF) from peripheral pulse wave in the presence of movement activity interferences, verified by additional analysis of ECG signal;

  • long-term monitoring in home conditions (for 30 days) with no inconvenience for the patient;

  • easy application and operation of the recorder as to be handled by older persons.

Design features:

  • optical sensor module for continuous recording of plethysmographic signal (PPG) – pulse wave;

  • two contact electrodes for episodic recording of ECG signal;

  • algorithm for detection of AF episodes from the PPG signal supported by the accelerometer signal

  • optical and vibroacoustic signaling of the events requiring the patient’s response

  • battery run-time over 24 hours, maintenance-free operation.

AF-watch records and analyzes the plethysmographic signal – pulse wave in continuous mode

while the electrocardiographic signal is acquired in episodic mode.

Cooperating with NOMED-AF Dock transmission station:

  • Recorder battery charging;

  • data transmission from Recorder to Remote Care Centre;

  • possibility to communicate with Monitoring Centre through 3G, WiFi, LAN
