Abstract
An ECG analysis system for use in conjunction with an ambulatory ECG recorder. The invention includes a playback deck which is capable of receiving and downloading information from a cassette tape to a dedicated digital analysis unit. The playback deck is capable of receiving information from the cassette tape during rewind of the tape therein as well as during playback of the tape. The dedicated digital analysis unit includes a superimposition template and a minute-by-minute ECG template which allow interaction between the dedicated digital analysis unit and the operator for simplification of analysis, manipulation, editing, and report generation. The system is capable of processing information from a cassette tape while it is being rewound in the playback deck and producing preliminary summary report information related to ECG data on the tape for use by a system operator before the tape completes its rewind operation. The playback deck also includes separate analog and digital circuit boards for isolating digital analysis operations from analog data manipulation operations and a speed control system for monitoring and correcting playback speeds of the tape in the playback deck.
