A viable wireless PC assisted alternative to studies of vectorcardiography

The development of an analog device to wirelessly modulate and record twelve cardiac leads, PC assisted is reported. The system, which has been developed using low cost components, contains only one signal conditioning stage and one stage for amplitude modulation with FM transmission/reception. Also...

Description
Summary:The development of an analog device to wirelessly modulate and record twelve cardiac leads, PC assisted is reported. The system, which has been developed using low cost components, contains only one signal conditioning stage and one stage for amplitude modulation with FM transmission/reception. Also it contains an interface to select the cardiac leads remotely, which is based in the transmission/decoding of audible dual frequency tones. The device has been tested on a group of volunteers simultaneously using a registered trademark electrocardiograph, to assess the performance of the new device. Furthermore, the experimental results indicate that the device is a tool suitable to conduct studies of vector-cardiography with maximum uncertainties of 20 % in the cardiac axis orientation measurement.
