Abstract
Systems, methods, and computer program product embodiments are disclosed for displaying cardiac signals based on a signal pattern. An embodiment operates by accessing an input cardiac signal. The embodiment matches a portion of the input cardiac signal to a known signal pattern. The embodiment then displays an indication of a degree of the match.
Claims20
A computer implemented method, comprising:
- accessing, by at least one processor, a first input cardiac signal using an electrode attached to a patient;
- receiving, from a user at a user interface by the at least one processor, a detection threshold;
- establishing, at the user interface by the user via the at least one processor, a reference point inside a previously stored known signal pattern, wherein the previously stored known signal pattern specifies a voltage variation over time that defines a morphology correlated with a disease;
- first matching, by the at least one processor, a first portion of the first input cardiac signal to the previously stored known signal pattern based on the detection threshold;
- in response to the first matching, first displaying on the user interface over one or more displays, by the at least one processor, the first portion of the first input cardiac signal side by side with a first portion of a second input cardiac signal, wherein the first portion of the second input cardiac signal occurs before, after, or simultaneously with the established reference point inside the matched previously stored known signal pattern;
- second matching, by the at least one processor, a second portion of the first input cardiac signal to the previously stored known signal pattern based on the detection threshold, wherein a size of the second portion of the first input cardiac signal is received from the user at the user interface;
- and
- triggering second displaying on the user interface over the one or more displays, by the at least one processor, the second portion of the first input cardiac signal side by side with a second portion of the second input cardiac signal in response to the second matching, wherein the second portion of the second input cardiac signal contains the established reference point inside the matched previously stored known signal pattern, wherein the second portion of the first input cardiac signal and the second portion of the second input cardiac signal are displayed vertically stacked above or below the displayed first portion of the first input cardiac signal and the displayed first portion of the second input cardiac signal on the user interface over the one or more displays.

A non-transitory computer-readable medium having instructions stored thereon that, when executed by at least one computing device, cause the at least one computing device to perform operations comprising:
- accessing a first input cardiac signal using an electrode attached to a patient;
- receiving, from a user at a user interface, a detection threshold;
- establishing, at the user interface by the user, a reference point inside a previously stored known signal pattern, wherein the previously stored known signal pattern specifies a voltage variation over time that defines a morphology correlated with a disease;
- first matching a first portion of the first input cardiac signal to the previously stored known signal pattern based on the detection threshold;
- in response to the first matching, displaying on the user interface over one or more displays the first portion of the first input cardiac signal side by side with a first portion of a second input cardiac signal, wherein the first portion of the second input cardiac signal occurs before, after, or simultaneously with the established reference point inside the matched previously stored known signal pattern;
- second matching a second portion of the first input cardiac signal to the previously stored known signal pattern based on the detection threshold, wherein a size of the second portion of the first input cardiac signal is received from the user at the user interface;
- and
- triggering displaying on the user interface over the one or more displays the second portion of the first input cardiac signal side by side with a second portion of the second input cardiac signal in response to the second matching, wherein the second portion of the second input cardiac signal contains the established reference point inside the matched previously stored known signal pattern, wherein the second portion of the first input cardiac signal and the second portion of the second input cardiac signal are displayed vertically stacked above or below the displayed first portion of the first input cardiac signal and the displayed first portion of the second input cardiac signal on the user interface over the one or more displays.
