Abstract

A hand-held electrocardiograph system with automatic analysis and interpretation is provided. The electrocardiograph includes an acquisition element adapted to be coupled to a patient through a set of relatively short leadwires and a hand-held, battery powered portable processing and display element coupled to the acquisition element and controlled through a graphical user interface.

Claims

1. An electrocardiograph system comprising:

an acquisition element adapted to be coupled to a patient through a set of relatively short leadwires; and

a hand-held, battery powered portable processing element coupled to the acquisition element through a connector cable and controlled through a graphical user interface.

2. The electrocardiograph system as in claim 1 wherein the processing element further comprises a display.

3. The electrocardiograph system as in claim 2 wherein the display further comprises a liquid crystal display.

4. The electrocardiograph system as in claim 3 wherein the liquid crystal display further comprises a color or monochrome graphical display with sufficient resolution to display waveforms.

5. The electrocardiograph system as in claim 2 wherein the display further comprises a touch screen interface.

6. The electrocardiograph system as in claim 1 wherein the processing element further comprises a compact flash card or similar memory expansion slot.

7. The electrocardiograph system as in claim 6 wherein the compact f lash expansion slot further comprises a compact flash read only memory disposed in the compact flash card expansion slot.

8. The electrocardiograph system as in claim 1 wherein the processing element further comprises an infrared transceiver for communications.

9. The electrocardiograph system as in claim 1 wherein the processing element further comprises a radio frequency transceiver for communications.

10. The electrocardiograph system as in claim 1 wherein the processing element further comprises an audio recording unit.

11. The electrocardiograph system as in claim 1 wherein the acquisition element further comprises a plurality of signal conditioning circuits.

12. The electrocardiograph system as in claim 1 wherein the acquisition unit further comprises a baseline sway filter.

13. The electrocardiograph system as in claim 1 wherein the acquisition unit further comprises a pacemaker pulse detector adapted to detect pacemaker signals.

14. The electrocardiograph system as in claim 1 wherein the acquisition unit further comprises analysis and interpretation.
