B.P. is CEO of Glasgow Neuro LTD which manufactures the Attys DAQ board. He has received a salary from Glasgow Neuro LTD which, however, did not provide any funding for this study. B.P. was involved in the design, data analysis, decision to publish, and preparation of the manuscript. However, this study is not about comparing different ECG measurement devices. The outcome of this study will be identical with other commercial data acquisition devices with identical specifications and the Attys does not alter the originally measured data in any way and thus does not introduce any bias. This does not alter our adherence to PLOS ONE policies on sharing data and materials. All data is available publicly and in its unprocessed format as measured by the Attys. There are no patents, products in development, or marketed products associated with this research to declare.
