Dipl. Ing. Christoph Zywietz, managing director of Biosigna, Institute for Biosignal Processing and System Analysis, was an internationally recognised expert in ECG signal analysis and worked in close cooperation with other companies and with the German Institute for Standardization (DIN), German Commission for Electrical, Electronic and Information Technologies of DIN and VDE, Working group diagnosis, European Committee for Standardization CEN, TC251 (where he was Convenor of WG5 for a number of years), ISO/IEC, SC 62D.

   He finished the School and High School in Berlin, and then he graduated in Studium Telecommunication Engineering from Staatl. Ingenieurschule Gauss (1956-1959). In the period 1959-1962 he was in Philips Valvo working on development of Valves and Semiconductors, and then in 1962-1968 he graduated in Studium Electrical Engineering/Telecommunication at Hannover University.

Since 1969 he was appointed at the Medical School in Hannover with these main tasks: Research, Service and Teaching in Biosignal Processing, Biocybernetics, Medical Informatics and ECG Computer Processing. In the same period he was lecturer at University of Hildesheim on Biosignal Processing, etc. as above. 

Since 1971 he was principal investigator of the Hannover ECG-system research group. He developed hardware and software for ECG analysis and biosignal processing in collaboration with industry and particularly the HES - ECG analysis programs (electrocardiogram/vectorcardiogram, exercise, Holter).

Since 1980 he represented the German Key Center in European Projects, i.e., CSE, SCP, CTS, OEDIPE and he was chairman of the Germany DIN/DKE working group on standardization of computerized electrocardiographs and development of new performance requirements. He was also the chairman of CEN TC 251 Working Group 5, which finalized the SCP-ECG Standard.

He was author or co-author of about 200 publications in scientific journals or proceedings and co-editor of the books: "Computer Applications on ECG and VCG analysis", North Holland, 1973, and "Computer ECG Analysis: Towards Standardization", North Holland, 1986.

He was one of the promoters and the key people of the OpenECG project, and hosted and chaired the 2nd OpenECG workshop in Berlin, Germany.
