Microprocessor-Based Solid-State ECG Recorder with ST Level Measurement for Ambulatory Patients

摘要

A survey is provided of instruments for recording physiological parameters over a long term, with particular reference to electrocardiograph ECG recorders. The development of a microprocessor-based ambulatory recorder is described. The design specifications and operational principles are given, but it is stated that proving tests on the hardware are in progress. The recorder stores samples of the ECG in solid state memory only on detection of ST segment (S-wave and T-wave) displacement. Up to eight 7sec strips of one channel ECG signal can be stored over a long term recording period, in addition to ST level trend data. Through online analysis, events of interest are recorded as they occur, dispensing with the lengthy analysis required by conventional cassette systems. An extensive bibliography is provided.
