In this paper, we presented the design of low-cost, compact and wireless 12 lead Electrocardiogram analog front-end (AFE) system using TI ADS 1198. ECG analog front-end (AFE) systems are designed with ASICs or custom designed ICs which are too expensive to be used. The main components of a conventional ECG system include instrumentation amplifiers, operational amplifiers that implement active filters...
Monitoring of ECG signal is used in medicine for multiple purposes. Measurements can be taken at any stage of patient's medical care, either as a preventative, diagnostical or recovery monitoring. Current wearable technology enables users and doctors to produce so far unprecedented amount of information. Processing of such measurements is usually a laborious and time consuming manual task. Automatic...
In the paper, a new version of a multichannel ECG measuring system ProCardio is introduced. The system was designed for measurement, processing, and evaluation of surface electrocardiograms using up to 144 passive or active ECG electrodes. For fast and convenient placement of electrodes, self-adhesive stripes with eight electrodes are used. To minimize the capacitive coupling and guarantee maximal...
Sensor based ECG signal acquisition methods are non-invasive method for diagnosing heart related diseases. A noise removal ECG signal provides certain details about the electrical activity of the heart. The main focus of this paper is to identify the suitable filtering method for ECG signal noise removal for physiological parameter measurement and monitoring using TCP/IP Protocol.

In this paper, we propose a two electrodes configuration for noncontact long-term cardiac monitoring. Our system was designed as an alternative to Holter devices. Unlike a traditional long-term monitoring equipment, our system is stationary and non-contact, the cardiac signal is acquired through a capacitive coupling between the sensor and the subject's body. The proposed system is the first prototype...
The long-term and real-time recording and analysis of a patient's heart rate can be helpful for medical staff to estimate a patient's prognosis. The long-term trends of various heart rate variability (HRV) parameters of a patient's condition may indicate disease development. In some cases, it may be used as feedback for providing suitable medical treatment. Because of the long-term purpose of recording...
