Abstract
Electrocardiograms have, since the beginning of the 1900s, been used as a noninvasive diagnostic method to reflect underlying heart conditions by measuring the electrical activity of the heart.
Novosense AB has developed a new technology for completely wireless recording of ECG. Their goal is to replace the stationary patient monitors and telemetry systems. Unlike today's technology, where a conductor connects each electrode with a monitor or telemetry unit, the signal transfers from the electrode wirelessly.
The purpose of this thesis is to integrate Novosense´s product for wireless recording of ECG with existing patient monitoring systems on the market. After completed thesis, Philips patient monitoring system will process the ECG... (More)
Electrocardiograms have, since the beginning of the 1900s, been used as a noninvasive diagnostic method to reflect underlying heart conditions by measuring the electrical activity of the heart.
Novosense AB has developed a new technology for completely wireless recording of ECG. Their goal is to replace the stationary patient monitors and telemetry systems. Unlike today's technology, where a conductor connects each electrode with a monitor or telemetry unit, the signal transfers from the electrode wirelessly.
The purpose of this thesis is to integrate Novosense´s product for wireless recording of ECG with existing patient monitoring systems on the market. After completed thesis, Philips patient monitoring system will process the ECG signal, which is a big profit for both demonstrations and validations.
The theory behind the cardiac anatomy, physiology and electrical activity is described in the report to identify the requirements of the unit, developed in this thesis. Also facts about Novosense and Philips patient monitoring system have been taken into consideration during the development, of the unit.
The receiving device and the wireless electrodes are replaced in this thesis by a demo unit, consisting of a LabVIEW program on a PC, which in a specified manner sends recorded demo signals via a USB interface. This allows the device to be tested and evaluated without Novosense´s products.
To control the data flow a microprocessor is used, which overall function is to receive serial data through the USB interface, and then address the correct D/A converter with a constant flow and synchronous update of the D/A converters outputs. Then the signal is adjusted before it finally is recorded by the Philips patient monitor.
The results of the thesis show that the demo signals can be received by Philips patient monitor and interpreted correctly. The unit, developed in this thesis, has thereby transformed the digital ECG leads to analog electrode potentials similar to those generated by a patient.
The performance can be further developed which is described in the report. (Less)
