Ambulatory ECG analysis system
First Claim
1. An ambulatory ECG monitoring system comprising:
- playback means for downloading ECG data from a data storage medium, said playback means including an analog circuit board means, a digital circuit board means including a microprocessor, and a data storage medium interface means, said analog circuit board means, said digital circuit board means and said data storage medium interface means being operatively associated with each other and positioned in structurally cooperative relationship with each other within said playback means.processor means for analysis, manipulation, and editing of data received from said playback means, andplayback/processor linking means for linking said playback means and said processor means for transfer of information between said playback means and said processor means,whereby said digital circuit board means said analog circuit board means are electrically isolated from each other to prevent operation of said digital circuit board means from causing electrical interface with data manipulation operations of said analog circuit board means.

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.

19. An ambulatory ECG monitoring system comprising:
-
playback means for downloading ECG data from a cassette tape, said playback means including a microprocessor, processor means for analysis, manipulation, and editing of data received from said playback means, and playback/processor linking means for linking said playback means and said processor means for transfer of information between said playback means and said processor means, said playback means further including a tape transport interface means, a speed control means and a clock track counter means, said tape transport interface means, said speed control means and said clock track counter means being operatively associated with each other and positioned in structurally cooperatively relationship with each other within said playback means, whereby, said microprocessor can monitor the speed of said cassette tape in said tape transport interface means by counting clock track pulses on said cassette tape to define an actual tape speed and compare said actual tape speed to an expected tape speed defined by said clock track counter means, and send a corrected tape speed value to said speed control means, said speed control means adjusting a voltage input to said tape transport interface means to adjust the speed of said tape transport interface means. - View Dependent Claims (20, 21)
