Systems and Methods for Generating and Applying Matrix Images to Monitor Cardiac Disease

A system for monitoring a progression of a cardiac disease in a patient by providing cardio-vibrational image matrixes generated using sensor data supplied by a wearable cardiac monitoring device, the system comprising:

• a non-volatile computer readable storage medium configured to store a plurality of cardio-vibrational measurements;
• and
• a plurality of operations stored as a plurality of computer executable instructions to a non-transitory computer readable media and/or encoded in hardware logic, wherein the plurality of operations is configured to
• access a plurality of cardio-vibrational signals obtained by at least one vibrational sensor monitoring a heart of the patient,
• generate, from the plurality of cardio-vibrational signals, cardio-vibrational measurements of a predetermined duration, the cardio-vibrational measurements comprising at least a plurality of S1 peaks and a plurality of S2 peaks, wherein the cardio-vibrational measurements are stored to the non-volatile computer readable storage medium;
• and
• transform the cardio-vibrational measurements of the predetermined duration into a cardio-vibrational image matrix, wherein transforming comprises
• segmenting the cardio-vibrational measurements of the predetermined duration into a plurality of adjacent cardiac portions each having a duration smaller than the predetermined duration, and
• plotting the plurality of adjacent cardiac portions using a plurality of pixel characteristic values mapped to parameter values of corresponding cardio-vibrational measurements to produce the cardio-vibrational image matrix, wherein plotting comprises
• on one axis, a time progression of the plurality of adjacent cardiac portions, and
• on another axis, the pixel characteristic values of each portion of the plurality of adjacent cardiac portions, wherein the pixel characteristic values of each respective portion comprise values representing at least an S1 parameter value corresponding to a respective S1 peak of the plurality of S1 peaks, and an S2 parameter value corresponding to a respective S2 peak of the plurality of S2 peaks, such that the cardio-vibrational image matrix represents, along the time progression of the plurality of adjacent cardiac portions, visible differences in timing and/or and intensity of at least the S1 parameter values of the cardiac portions and the S2 parameter values of the cardiac portions;
• and
• output the cardio-vibrational image matrix as an image file for use in monitoring the progression of the cardiac disease in the patient.
