Abstract
A method is disclosed for displaying patient ECG data. The method includes receiving ECG data including an ECG waveform; receiving analyzed ECG data including arrhythmic events; generating an indicia of the detected arrhythmic event; and displaying the indicia of the detected arrhythmic event in relation to the ECG waveform at a position associated with a time of the detected arrhythmic event. A system for displaying patient ECG data is also disclosed.
Core Innovation
The invention relates to displaying patient ECG data on an electronic device where analyzed ECG data includes a detected arrhythmic event. The system generates an indicia of the detected arrhythmic event and displays the indicia in relation to the ECG waveform at a position associated with a time of the detected arrhythmic event.
The invention classifies the patient into one of a plurality of patient groups based on a detected severity or a detected recency of the detected arrhythmic event. For each patient group, a group indicia is generated and displayed, and each group indicia includes an identification of one or more patients classified into that patient group.
For multiple patients, the invention displays a plurality of group indicia and/or a display of indicia of a plurality of patients, each including an ECG waveform and indicia of a detected arrhythmic event associated with the respective patient. The displayed indicia are sorted based on a classifying of each patient into one of the plurality of patient groups and may also be sorted as a sequence based on a number, a recency, or a severity of one or more detected arrhythmic events for each patient.
In addition to event indicia, the invention includes receiving and displaying indicia of a patient’s compliance or lack of compliance with a device usage procedure or a prescribed treatment. The document also describes workflows in which a health care provider requests to view ECG data and the system transmits one or more images showing indicia of the detected arrhythmic event in relation to the ECG waveform at a position associated with the time of the detected arrhythmic event.
Claims Coverage
The document includes four independent claims covering methods, systems, and a handheld device. Across these independent claims, the core inventive features are event indicia positioned to event time on an ECG waveform, patient grouping based on detected severity/recency, multi-patient display with sorting based on group membership and event attributes, and compliance/lack-of-compliance indicia.
Ecg event indicia positioned by event time and patient grouping display
Receiving ECG data including an ECG waveform; receiving analyzed ECG data including a detected arrhythmic event; generating an indicia of the detected arrhythmic event; displaying the indicia in relation to the ECG waveform at a position associated with a time of the detected arrhythmic event; classifying the patient into one of a plurality of patient groups based on a detected severity or a detected recency of the detected arrhythmic event; generating a group indicia associated with each of the plurality of patient groups; and displaying the plurality of group indicia, each group indicia including an identification of one or more patients classified into the patient group.
Multi-patient ECG display with sorting based on patient groups
Receiving ECG data including an ECG waveform; receiving analyzed ECG data including a detected arrhythmic event; generating an indicia of the detected arrhythmic event; displaying the indicia in relation to the ECG waveform at a position associated with a time of the detected arrhythmic event; classifying the patient into one of a plurality of patient groups based on a detected severity or a detected recency of the detected arrhythmic event; generating a display of indicia of a plurality of patients, each including an ECG waveform and indicia of a detected arrhythmic event associated with each respective patient; and sorting the displayed indicia of the plurality of patients based on a classifying of each patient into one of the plurality of patient groups.
System for sorting multiple patients’ ECG event indicia sequences
A system comprising a data storage device storing instructions for displaying patient ECG data; and a processor configured to execute the instructions to perform a method comprising receiving ECG data including an ECG waveform; receiving analyzed ECG data including a detected arrhythmic event; generating an indicia of the detected arrhythmic event; associating the indicia with the ECG waveform at a time of the detected arrhythmic event; generating a display of indicia of a plurality of patients, each including an ECG waveform and indicia of a detected arrhythmic event associated with each respective patient; sorting a sequence of the displayed indicia of the plurality of patients based on a number, a recency, or a severity of one or more detected arrhythmic events for each patient; and a display device configured to display the indicia in relation to the ECG waveform at a position associated with a time of the detected arrhythmic event.
Handheld display of ECG event indicia and compliance indicia
A handheld device comprising a memory device storing instructions for displaying patient ECG data on the handheld device; and a processor configured to execute the instructions for receiving an ECG waveform or image of an ECG waveform, based on analyzed ECG data, and indicia of a detected arrhythmic event; generating a display of the indicia in relation to the ECG waveform or image of the ECG waveform at a position associated with a time of the detected arrhythmic event; generating an indicia of a patient's compliance or lack of compliance with a device usage procedure or a prescribed treatment; and a display unit configured to display the indicia of the patient's compliance or lack of compliance.
Across the independent claims, the document centers on displaying ECG waveform data together with indicia of detected arrhythmic events placed at positions associated with event time. It also covers grouping and multi-patient display, including sorting sequences based on patient group classification and event attributes, and it extends to handheld display of event indicia and compliance/lack-of-compliance indicia.
