Systems and methods for improving visibility of features of physiologic signal segments

A system for improving visibility of features of a physiologic signal segment that is to be displayed within a display band having a specified height between an upper boundary and a lower boundary of the display band, the system comprising:

• memory configured to store specific executable instructions;
• and
• one or more processors configured to execute the specific executable instructions to:
• obtain the physiologic signal segment, which is indicative of physiologic activity of a patient for a period of time that includes a plurality of cycles of the physiologic activity, wherein the physiologic signal segment has an original signal segment range that extends from an original minimum peak amplitude of the physiologic signal segment to an original maximum peak amplitude of the physiologic signal segment;
• divide the physiologic signal segment into a plurality of sub-segments;
• determine a sub-segment minimum peak amplitude and a sub-segment maximum peak amplitude, for each of the plurality of sub-segments, to thereby determine a plurality of sub-segment minimum peak amplitudes and a plurality of sub-segment maximum peak amplitudes;
• determine a new minimum peak amplitude based on the plurality of sub-segment minimum peak amplitudes, and a new maximum peak amplitude based on the plurality of sub-segment maximum peak amplitudes;
• determine a new display range as being from the new minimum peak amplitude to the new maximum peak amplitude, wherein the new display range is narrower than the original signal segment range;
• and
• cause display, within the display band having the specified height, of a portion of the physiologic signal segment that is within the new display range, such that the upper boundary of the display band corresponds to the new maximum peak amplitude, and the lower boundary of the display band corresponds to the new minimum peak amplitude.

One or more processor readable non-transitory storage devices having instructions encoded thereon which when executed cause one or more processors to perform a method for improving visibility of features of a physiologic signal segment that is to be displayed within a display band having a specified height between an upper boundary and a lower boundary of the display band, the method comprising:

• obtaining the physiologic signal segment, which is indicative of physiologic activity of a patient for a period of time that includes a plurality of cycles of the physiologic activity, wherein the physiologic signal segment has an original signal segment range that extends from an original minimum peak amplitude of the physiologic signal segment to an original maximum peak amplitude of the physiologic signal segment;
• dividing the physiologic signal segment into a plurality of sub-segments;
• determining a sub-segment minimum peak amplitude and a sub-segment maximum peak amplitude, for each of the plurality of sub-segments, to thereby determine a plurality of sub-segment minimum peak amplitudes and a plurality of sub-segment maximum peak amplitudes;
• determining a new minimum peak amplitude based on the plurality of sub-segment minimum peak amplitudes, and a new maximum peak amplitude based on the plurality of sub-segment maximum peak amplitudes;
• determining a new display range as being from the new minimum peak amplitude to the new maximum peak amplitude, wherein the new display range is narrower than the original signal segment range;
• and
• causing displaying, within the display band having the specified height, of a portion of the physiologic signal segment that is within the new display range, such that the upper boundary of the display band corresponds to the new maximum peak amplitude, and the lower boundary of the display band corresponds to the new minimum peak amplitude.
