Conducting System 1. This paper has grown out of an earlier one (Buxton, Reeves, Fedorkow, Smith, and Baecker 1979) which was presented at the 64th Convention of the Audio Engineering Society. While certain parts of the text are the same, the bulk of the paper has been rewritten and expanded to better represent the current state of the system and the interests of the readers of Computer Music Journal.
A real time system for graphically displaying premature ventricular beat trends is described. The system consists of analog detector circuits coupled to a Fortran based software program for premature ventricular beat processing. The software program runs four independent channels and has three available analysis modes: a "counting" mode which provides a running total of counts to date; an "averaging" mode which displays average number of events over time, and a "ratio" mode which provides an output reflecting changes in the ratio of premature ventricular beats to all beats. Various scale factors can be applied to accommodate differing background states. The system's strengths lie in its simplicity, accuracy, and simultaneous analog display of both the original ECG signal as well as the derived quantitative data.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
