摘要： The system and method defined herein are intended to detect, monitor and characterize in a non-invasive way cardiac arrhythmias of a patient that are associated with the development of atrial arrhythmia and increased risk of ischemic cerebral stroke. The system consists of a portable device with integrated sensors for biosignals; integrated modules in the portable device for recognition of intermittent atrial arrhythmia episodes; a module for characterization of the distribution of atrial arrhythmia episodes aiming to assess disease progression. The proposed is a technical solution allows for long-term monitoring of atrial fibrillation in a non-invasive way for the patient. If a non-documented atrial arrhythmia is detected by automatic means during the long-term monitoring, a physician is informed by e-mail by sending the electrocardiogram of the said arrhythmia episode. If the physician confirms diagnosis of atrial fibrillation, a recommendation for immediate medical attention is sent to patient's smart device.

摘要： This invention discloses a novel method for monitoring and analyzing human cardiovascular functions and the equipment implementing the said method. It presents a portable device with the implemented measurement-analytical method that enables monitoring of heart function and selectively of brain tissue functions by measuring electrical bioimpedance along with electrocardiogram (ECG) and photoplethysmogram (PPG) measurements.
The presented method and equipment allow to measure two types of cardiovascular parameters, to process, synchronize, analyze them and thus to obtain information about the state of cardio and brain vascular activity changing over time. Also, spatial analysis is applied to the measured bioimpedance data which together with the temporal analysis data allows determining the patient's condition and how it changes after stroke.
