Patent number: 11445968Abstract: Heart condition and function can be quantified using repolarization measures and/or repolarization indices derived from a time-frequency transform of an electrocardiogram, e.g., based on points in time associated with the T wave. The electrocardiograms, time-frequency maps derived therefrom, and/or indices obtained by analysis of the time-frequency maps and electrocardiograms may be assembled into a user interface. Further embodiments are described.Type: GrantFiled: January 10, 2020Date of Patent: September 20, 2022Assignee: HEART TEST LABORATORIES, INC.Inventors: Guangren Chen, David Krubsack, Mark Hilz

Patent number: 11445918Abstract: Diastolic function may be assessed by operating one or more machine-learned computational models on electrocardiograms or electrocardiogram-derived features to compute quantitative diastolic indicators, including estimates of echocardiography parameters conventionally measured by echocardiography. In various embodiments, parameters derived from time-frequency transforms of the electrocardiograms are used as input to the model(s) and/or computed within the model(s).Type: GrantFiled: August 27, 2020Date of Patent: September 20, 2022Assignee: HEART TEST LABORATORIES, INC.Inventors: Aaron Peterson, Partho Sengupta, David Krubsack

Patent number: 11336034Abstract: In electrocardiography (ECG) system, a patient cable connecting one or more electrodes to a processing device for processing ECG signals may include one or more electrode connectors mechanically keyed to respective electrodes and/or a device connector mechanically and/or electronically keyed to a cable connector of the processing device. In some embodiments, keying between the cable and electrode is achieved, for example, with an electrode including a hollow-post portion that defines a bore in conjunction with a post protruding from an arm of the electrode connector that is sized to fit within the bore.Type: GrantFiled: July 24, 2018Date of Patent: May 17, 2022Assignee: HEART TEST LABORATORIES, INC.Inventors: Mark Hilz, Paul Klotz, Mark Tiegs

Patent number: 10856756Abstract: Electrocardiograms can be analyzed in the time-frequency domain, following conversion into time-frequency maps, to determine characteristics or features of various waveforms, such as waveform morphology and/or the amplitude(s) and location(s) (in time and/or frequency) of one or more extrema of the waveform. Based on comparison of the extrema against thresholds and/or against each other, disease conditions may be determined.Type: GrantFiled: September 11, 2018Date of Patent: December 8, 2020Assignee: HEART TEST LABORATORIES, INC.Inventors: David Krubsack, Aaron Peterson
