Abstract

An electrocardiograph device and methods of navigating displays of such a device are disclosed. In one example, an electrocardiograph device includes a display, a plurality of electrocardiograph signal leads, and a programmable circuit. The programmable circuit is configured to receive electrical signals via the electrocardiograph signal leads representative of a heartbeat of a patient. The programmable circuit is configured to generate a user interface to be presented on the display, the user interface comprising a lead display including a screen layout including a plurality of waveform regions. The waveform regions display a waveform corresponding to an electrical signal from one of the leads over a time interval including at least one heartbeat period. Selection of a region causes display of an extended waveform region displaying a waveform over a second time interval that is longer than the first time interval, and which includes a plurality of heartbeat periods.

Claims

1. An electrocardiograph device comprising:

a display;

a plurality of electrocardiograph signal leads configured for electrical connection to a patient;

a programmable circuit operatively connected to the display and to the plurality of electrocardiograph signal leads, the programmable circuit configured to receive electrical signals via the electrocardiograph signal leads representative of a heartbeat of a patient, wherein the programmable circuit is further configured to;

generate a user interface to be presented on the display, the user interface comprising;

a lead display including a visual depiction of a location of each of the plurality of electrocardiograph signal leads; and

a screen layout including a plurality of waveform regions, the waveform regions being adjacent to one another and each displaying a waveform corresponding to an electrical signal from one of the plurality of electrocardiograph signal leads over a first time interval including at least one heartbeat period; and

upon receiving selection of a region of the user interface, display an extended waveform region associated with one or more of the electrocardiograph signal leads,

the extended waveform region displaying a waveform corresponding to the electrical signal from one of the plurality of electrocardiograph leads over a second time interval that is longer than the first time interval;

the extended waveform region having an extended waveform region width, the extended waveform region width being greater than a waveform region width of one of the waveform regions and including a plurality of heartbeat periods.

2. The electrocardiograph device of claim 1, wherein the display comprises a touch screen display, and wherein selection of the region comprises touching the region to be selected.

3. The electrocardiograph device of claim 1, wherein the region comprises a view toggle button, wherein, in response to selection of the view toggle button, the lead display cycles among a plurality of views, wherein the extended region is included within at least one of the plurality of views.

4. The electrocardiograph device of claim 3, wherein each of the plurality of views corresponds to a different layout of regions within the lead display.

5. The electrocardiograph device of claim 1, wherein the region comprises one of the plurality of waveform regions.

6. The electrocardiograph device of claim 5, wherein, upon display of the extended waveform region, one or more of the plurality of waveform regions of the lead display are hidden from view.

7. The electrocardiograph device of claim 6, wherein a selection of the extended waveform region reverts the lead display to displaying each of the plurality of waveform regions including the waveform regions hidden from view while the extended waveform region is displayed.

8. The electrocardiograph device of claim 1, wherein the user interface further includes a leads region selectable by a user, wherein, upon receiving selection of the leads region, the programmable circuit is further programmed to display a second screen layout including a plurality of waveform regions including waveform regions corresponding to electrical signals from one or more of the plurality of electrocardiograph signal leads not presented in the lead display.

9. The electrocardiograph device of claim 1, wherein the lead display includes one or more test action buttons.

10. The electrocardiograph device of claim 1, wherein the visual depiction of the lead display includes an image of a torso depicting locations of leads placed on the patient.

11. The electrocardiograph device of claim 10, wherein, upon selection of the image of the torso, displaying an enlarged image of the torso overlaying at least a portion of one or more of the plurality of waveform regions.

12. A method of operating an electrocardiograph device, the method comprising:

receiving one or more signals from a plurality of electrocardiograph signal leads that are attached to a patient;

allowing for selection of a display mode on a display of the electrocardiograph device to display a lead display providing an indication of an electrical signal from one or more of the plurality of electrocardiograph signal leads;

allowing for selection of a view toggle button to cause the display mode to cycle among a plurality of screen layouts for the display, including;

a first screen layout including a region occupying a majority of the display, the region showing waveforms from each of the plurality of electrocardiograph signal leads; and

a second screen layout including an extended region showing a waveform from one of the plurality of electrocardiograph signal leads, with the waveform on the extended region having a time duration that is longer than the first screen layout so that an additional waveform portion of the one of the plurality of electrocardiograph signal leads is shown on the display; and

allowing for selection of one of the waveforms on the first screen layout of the display, thereby causing the electrocardiograph device to display the extended region associated with one or more of the electrocardiograph signal leads, the extended region at least partially overlaying one or more remaining regions adjacent to the selected region.

13. The method of claim 12, wherein selecting one of the plurality of regions on the display comprises touching the region on the display, wherein the display includes a touch screen display.
