Medical device with modifiable view of an electrocardiogram

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.

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.
