Abstract

A cardiograph having a keypad includes an internal disc drive for reading a floppy disc provided to the drive. ROM and RAM in the cardiograph incudes a program for loading a macro instruction contained on a floppy disc into the cardiograph RAM. Another program executes the macro instruction responsive to an operator-actuated input. The macro instruction includes keypad codes which provide patient data and configuration and control instructions to the cardiograph. Several special function codes which do not correspond to keypad codes are provided for pausing the macro instruction, ending the instruction and other special functions. In one aspect, patient data is copied onto the floppy disc from a hospital information system and thereafter provided to the cardiograph preliminary to a cardiographic recording session with the patient.

Claims

1. A method for enhanced efficiency in the utilization of a cardiograph which includes a digital processor, memory and a keypad which includes a plurality of keys for providing instructions and data to said cardiograph which relate to collection and display of cardiographic data, said method comprising the steps of:

providing a macro instruction for initiating a plurality of signals which simulate actuation of said plurality of keys in a predetermined order for providing instruction and data relating to collection and display of cardiographic data for a selected patient;

storing said macro instruction within portable storage media;

temporarily coupling said portable storage media to said digital processor;

connecting said cardiograph to said selected patient;

initiating execution of said macro instruction; and

collecting cardiographic data for said selected patient in response to execution of said macro instruction.

2. The method for enhanced efficiency in the utilization of a cardiograph according to claim 1, further including the steps of:

providing a plurality of macro instructions, each of said plurality of macro instructions for initiating a plurality of signals which simulate actuation of said plurality of keys in a predetermined order for providing instruction and data relating to collection and display of cardiographic data for an associated patient;

storing said plurality of macro instructions within portable storage media;

selecting a particular one of said plurality of macro instructions;

initiating execution of said particular one of said macro instructions; and

collecting cardiographic data for a selected patient associated with said particular one of said plurality of macro instructions in response to execution of said particular one of said plurality of macro instructions.

3. The method for enhanced efficiency in the utilization of a cardiograph according to claim 2, further including the step of generating an indication to an operator of said cardiograph that said particular one of said plurality of macro instructions has been executed.

4. The method for enhanced efficiency in the utilization of a cardiograph according to claim 2, wherein said cardiograph includes a display and wherein said method further includes the step of displaying each macro instruction and particular data for an associated patient.

5. The method for enhanced efficiency in the utilization of a cardiograph according to claim 2, wherein each of said plurality of macro instructions is associated with a plurality of attributes and wherein said method further includes the step of sorting said plurality of macro instructions by a selected attribute prior to said step of selecting a particular one of said plurality of macro instructions.

6. A medical testing device comprising:

at least one transducer for collecting patient data;

a display;

a processor coupled to said at least one transducer and said display for controlling the collection and display of data;

a memory device coupled to said processor for storing said processor instructions and data;

a keypad having a plurality of keys operatively coupled to said processor and said memory device for providing instructions and data thereto in response to operator actuation of said plurality of keys;

a disc drive unit operatively connected to said processor and said memory device;

a storage disc adapted to be inserted within said disc drive unit, said storage disc including a macro instruction for initiating a plurality of signals which simulate actuation of said plurality of keys in a predetermined order for providing instruction and data relating to collection and display of data for a selected patient;

means for initiating execution of said macro instruction in response to an operator generated signal.

7. The medical testing device according to claim 6, wherein said at least one transducer comprises a plurality of electrodes for detecting electrical activity resulting from a patient'"'"'s heart.
