Abstract
Portable, two-way ECG data-storage apparatus for the selective window-capturing of successive plural-lead ECG data records. The apparatus receives its information from the analogue output terminals in a conventional ECG machine, and operates a store multiple-lead data in flagged time-windowed fashion in order to assure stable signal information and efficient meory use. Playback can occur either directly in an analogue manner back to any selected ECG machine, and/or audibly for listening to by a user or for transtelephonic transmission.
Claims5
Portable, two-way ECG data-storage apparatus for the selective window-capturing, in the successive records, of plural-lead ECG data comprising
- a central digital processor and an associated semiconductor memory,
- an input/output interface structure selectively coupleable to the input and output analog terminals in an external ECG machine, said structure including analog/digital conversion means, operatively connected to said processor and memory for transferring ECG data to and from said memory,
- user-interface control means operatably connected to said processor, operable selectively, in a capture/storage mode, to effect, via processor operation, the capture and storage in said memory (for a limited preselected time window only) of converted analog ECG data arriving at said interface structure, and in a retrieve/broadcast mode to supply, for outputting via said interface structure, converted digital data then stored in said memory.
Portable, two-way ECG data-storage apparatus for the selective window-capturing, in the successive records, or plural lead ECG data comprising:
- a central digital processor and an associated semiconductor memory,
- an input/output interface structure selectively alternately coupleable to the input and output analog terminals in an external ECG machine one at a time, said structure including analog/digital conversion means, operatively connected to said processor and memory for transferring ECG data from such output analog terminal to said memory at a time when said structure is coupled thereto and from said memory to such input analog terminal at an alternate time when said structure is coupled thereto,
- user-interface control means operatably connected to said processor, operable selectively, in a capture/storage mode, to effect via processor operation, the capture and storage in said memory of converted analog ECG data arriving at said interface structure, and operable alternately, in a retrieve/broadcast mode to supply, for outputting via said interface structure, converted digital data then stored in said memory.
