Abstract

Various systems, methods, and devices related to modifying views of a multi-lead electrocardiogram (ECG), as well as identifying notations associated with the multi-lead ECG, are described. An example method includes displaying graphical elements in a first arrangement. The graphical elements respectively depict electrical signals indicative of an electrical activity of a heart. The example method further includes detecting a signal indicative of a display selection, and, based on the display selection, rearranging the graphical elements from the first arrangement to a second arrangement.

Claims (48)

1. A defibrillator, comprising:

a memory;

a sensor configured to detect a user input, the user input comprising a touch input, a device movement input, a voice input, or a button input;

a measurement circuit configured to detect an electrocardiogram (ECG) of a patient;

a treatment circuit configured to output an electrical shock;

a user interface (UI) configured to present waveforms in a grid according to the selected grid arrangement; and

a processor configured to:

generate the waveforms representing relative electrical potentials in the ECG over time; and

determine, by analyzing the user input, a selected grid arrangement from among a portrait arrangement or a landscape arrangement for presenting the waveforms in the grid, the grid comprising a row of the waveforms positioned side by side each other, and a column of the waveforms positioned above and below each other;

identify, via the UI, a touch associated with one of the waveforms; and

update the waveform with which the annotation is associated to be overlaid by a notation in response to the identifying of the touch.

2. The defibrillator of claim 1 , wherein the UI is configured to present the waveforms in the grid in a Cabrera sequence.

3. The defibrillator of claim 2 , wherein the UI is configured to present the waveforms in a non-Cabrera sequence.

4. A medical device, comprising:

a user interface (UI) configured to present waveforms in a grid; and

a processor configured to:

generate waveforms representing relative electrical potentials in an electrocardiogram (ECG); and

determine, by analyzing a user input detected by a sensor, a selected grid sequence from among a Cabrera sequence or a non-Cabrera sequence for presenting the waveforms in the grid, the grid comprising a row of the waveforms positioned side by side each other, and a column of the waveforms positioned above and below each other;

identify, via the UI, a touch associated with one of the waveforms; and

update the waveform with which the annotation is associated to be overlaid by a notation in response to the identifying of the touch.

5. The medical device of claim 4 , wherein the UI is configured to present the waveforms in a portrait arrangement.

6. The medical device of claim 4 , wherein the UI is configured to present the waveforms in a landscape arrangement.

7. The medical device of claim 4 , wherein the processor is further configured to:

cause the UI to rearrange the waveforms in the grid according to an alternate grid sequence, the alternate grid sequence being different than the selected grid sequence.

8. The medical device of claim 7 , wherein the selected grid sequence comprises the Cabrera sequence and the alternate grid sequence comprises the non-Cabrera sequence, or

wherein the selected grid sequence comprises the non-Cabrera sequence and the alternate grid sequence comprises the Cabrera sequence.

9. The medical device of claim 4 , wherein the UI is configured to present the grid in the Cabrera sequence and a portrait arrangement, or

wherein the UI is configured to present the grid in the non-Cabrera sequence and a landscape arrangement.

10. The medical device of claim 4 , wherein the user input comprises a touch input, a device movement input, a voice input, or a button input.

11. The medical device of claim 4 , further comprising:

the sensor configured to detect a touch moving against a surface of the UI as the user input.

12. The medical device of claim 4 , further comprising:

the sensor comprising a gyroscope or an accelerometer configured to detect a physical rotation as the user input.

13. A method, comprising:

detecting, by a sensor, a user input;

generating waveforms representative of an electrocardiogram (ECG);

determining, by analyzing the user input, a selected grid arrangement from among a portrait arrangement or a landscape arrangement for the waveforms being presented in a grid, the grid comprising a row of the waveforms positioned side by side each other, and a column of the waveforms positioned above and below each other;

presenting, by a user interface (UI), the waveforms in the grid according to the selected grid arrangement;

identifying, via the UI, a touch associated with one of the waveforms; and

updating the waveform with which the annotation is associated to be overlaid by a notation in response to the identifying of the touch.

14. The method of claim 13 , wherein presenting, by the UI, the waveforms in the grid according to the selected grid arrangement comprises presenting the waveforms in an anatomical orientation.

15. The method of claim 13 ,

wherein presenting, by the UI, the waveforms in the grid according to the selected grid arrangement comprises presenting the waveforms in a non-anatomical orientation.

16. The method of claim 13 , wherein presenting, by the UI, the waveforms in the grid according to the selected grid arrangement comprises presenting the waveforms in the portrait arrangement, an upper-left waveform in the grid corresponding to a voltage of a left arm relative to a voltage of a virtual terminal.

17. The method of claim 13 , wherein presenting, by the UI, the waveforms in the grid according to the selected grid arrangement comprises presenting the waveforms in the landscape arrangement, an upper-left waveform in the grid corresponding to a Lead I.

18. The method of claim 13 , wherein presenting, by the UI, the waveforms in the grid comprises presenting a group of the waveforms side-by-side in the row.

19. The method of claim 13 , wherein presenting, by the UI, the waveforms in the grid comprises presenting a group of the waveforms vertically in the column.

20. The method of claim 13 , wherein presenting, by the UI, the waveforms in the grid comprises presenting a first group of the waveforms in the row and presenting a second group of the waveforms in the column.
