Abstract
Systems and methods for determining prevalence of a cardiac phenomenon based on electrophysiological (EP) data from a tissue of a body are provided. The EP data is measured by at least one sensor disposed on at least one medical device that is positionable near the tissue of the body. A system includes an electronic control unit communicatively coupled to a display device and configured to, for each of the plurality of locations, detect, at each of a plurality of discrete times occurring during a predetermined time period, whether a cardiac phenomenon occurs at the location based on the EP data, determine a prevalence of the cardiac phenomenon based on the detecting, and display information indicative of the determined prevalence of the cardiac phenomenon on the display device.

A system for determining prevalence of a cardiac phenomenon based on electrophysiological (EP) data from a tissue of a body, the EP data measurable at a plurality of locations by at least one sensor disposed on at least one medical device that is positionable near the tissue of the body, the system comprising:
- an electronic control unit (ECU) communicatively coupled to a display device and configured to:
- for each of the plurality of locations:
- detect, at each of a plurality of discrete times occurring during a predetermined time period, whether a cardiac phenomenon occurs at the location based on the EP data, the plurality of discrete times occurring at a sampling frequency that defines a regular interval between consecutive discrete times of the plurality of discrete times;
- determine a prevalence of the cardiac phenomenon based on the detecting by dividing a number of the plurality of discrete times when the cardiac phenomenon occurs by a total number of the plurality of discrete times;
- and
- display information indicative of the determined prevalence of the cardiac phenomenon on the display device.
A computer-implemented method of determining prevalence of a cardiac phenomenon based on electrophysiological (EP) data from a tissue of a body, the EP data measured at a plurality of locations by at least one sensor disposed on at least one medical device that is positionable near the tissue of the body, the method comprising:
- for each of the plurality of locations:
- detecting, at each of a plurality of discrete times occurring during a predetermined time period, whether a cardiac phenomenon occurs at the location based on the EP data, the plurality of discrete times occurring at a sampling frequency that defines a regular interval between consecutive discrete times of the plurality of discrete times;
- determining a prevalence of the cardiac phenomenon based on the detecting by dividing a number of the plurality of discrete times when the cardiac phenomenon occurs by a total number of the plurality of discrete times;
- and
- displaying information indicative of the determined prevalence of the cardiac phenomenon.
A processing apparatus for determining prevalence of a cardiac phenomenon based on electrophysiological (EP) data from a tissue of a body, the EP data measurable at a plurality of locations by at least one sensor disposed on at least one medical device that is positionable near the tissue of the body, the processing apparatus configured to:
- for each of the plurality of locations:
- detect, at each of a plurality of discrete times occurring during a predetermined time period, whether a cardiac phenomenon occurs at the location based on the EP data, the plurality of discrete times occurring at a sampling frequency that defines a regular interval between consecutive discrete times of the plurality of discrete times;
- determine a prevalence of the cardiac phenomenon based on the detecting by dividing a number of the plurality of discrete times when the cardiac phenomenon occurs by a total number of the plurality of discrete times;
- and
- cause information indicative of the determined prevalence of the cardiac phenomenon to be displayed on a display device.
