In this paper we propose using the ECG bandgap storage area for coding high frequency details of the signal. Authorization-dependent access to these details allows privileged users for high precision analysis, while regular users with an access to standard resolution signal are still able to correctly calculate essential parameters. The proposed algorithm performs limited ECG interpretation, analysis...
With the rapid advancements of biomedical engineering and wireless communication it is possible to develop body sensor networks (BSN) which support a range of applications including medical and healthcare systems. The aim of the research is to propose a prototype of BSN-based wearable wireless monitoring system optimized to monitor patient's activity and physiological signals. The system consists...
This paper presents the use of bandwidth gap for embedding supplementary digital data into the ECG record without changing its ability to diagnose. The gap results from overestimation of the constant sampling frequency which is greater than the local bandwidth of cardiac components in large parts of the ECG record. The proposed algorithm starts with conventional beat detection and wave delineation...
Common use of telemedical recordings performed in home care conditions and interpreted automatically justifies the need for a reliable signal-to-noise estimate. We propose new noise measurement technique based on a time-frequency model of noise computed in a quasi-continuous way. The proposed method is dedicated to ECG and uses automatically recognized cardiac components for temporal adaptation of...
Health monitoring and body area network (BAN) applications require wireless intelligent monitoring devices and information systems. The aim of our research is to propose a prototype of wearable wireless monitoring device optimized to supervising the patient and examine the influence of movement on the heart rate during normal daily activities. Main purpose of the proposed system consists in simultaneous...
This paper presents the usage of purposely adapted ECG interpretation software as a classroom tool providing reliable reference values of most diagnostic parameters for ECG records from any source. The software maintains the commercial reliability and no part of its source code is disclosed. Additional checkpoints and data switches between the internal procedures (e.g. beat detection, classification,...
This paper presents a personal system and software architecture dedicated for cardiac telerehabilitation. The key idea of the hardware configuration and the software implementation is the integration of a mobile device and an ECG recorder with the application of wireless technologies: Bluetooth, GPS and GPRS. The main goal of the system is the reliable detection of the QRS complex providing a cardiovascular...
In this paper we describe a wearable ubiquitous healthcare monitoring system that integrates electrocardiogram (ECG device) and an accelerometer sensor with a mobile device in a Bluetooth-based body surface network (BSN). Our research focused on the right connection of the hardware units, combination of the detection of QRS complexes, calculation of heart rate (HR) and the detection of human falls...
The introduction of distributed ECG interpretation is currently limited by the computational capacity of a battery-operated wearable recorder. The relations between human experts in cardiology are generalized in this paper and considered as a pattern of co-operation between computerized interpretation centers. Studying the cardiologist's practice we found out that during the years the range of family...
