Computeranalyse des korrigierten, orthogonalen Kardiogramms
Es wird ein Uberblick uber die Entwicklung der orthogonalen Elektrokardiografie und Vektorkardiografie gegeben. Die in der Literatur zum Teil recht unterschiedliche Terminologie wird erlautert, die elektrophysiologischen Voraussetzungen zur Gultigkeit der korrigierten, orthogonalen Elektrokardiografie werden ausfuhrlich dargestellt.
Untersuchungen zur Reliabilität von Mustererkennungs-Algorithmen für die P-Wellen orthogonaler Elektrokardiogramme
On the Reliability of Pattern Recognition Algorithms for ECGs Judging the performance of pattern recognition algorithms in ECG analysis on an objective basis still presents a severe problem because of the heuristic nature of the criteria used- The paper illustrates that problem by way of P-wave detectors for ECGs. We want to focus on the external reliability of the algorithms. The term external reliability is closely related to condition or robustness. Here we are interested in the variation of the output of an algorithm when the input data are slightly altered. This pertains to the problem of how the biological variance of the ECGs is mapped into the variance of algorithm output. We may sa…
Kriterien für die Auswahl von Elektronischen Rechenanlagen für Biomedizinische Forschungsinstitute
Computers are now a recognized tool in biomedical research. They are used for the evaluation of data on one hand and on the other hand for data acquisition and control of experiments. Based on our experience, some suggestions concerning the structure of a mini-computer system suitable for a research laboratory are made. According to the two major classes of application, two sets or requirements arise. We argue that it is effective to use this system for data reduction and evaluation because a large percentage of tasks require program development or at least specific input data handling. Therefore, we call for a multi-user time-sharing system which should be equipped with a set of commands t…
