1. A method comprising:
- using one or more electrodes placed on a patient, measuring one or more electrocardiograms associated with one or more respective leads;
using a processor, converting the one or more electrocardiograms by time-frequency transform into one or more corresponding two-dimensional time-frequency maps; and
generating a user interface displaying, for at least one of the one or more electrocardiograms, at least a portion of the electrocardiogram and, in temporal alignment therewith, a temporally coextensive portion of the corresponding time-frequency map.

Abstract
Heart condition and function can be visualized and/or quantified using time-frequency maps derived from the time-frequency transform of one or more electrocardiograms. 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.

16. A heart test system comprising:
-
an electrode interface configured to receive one or more electrocardiogram signals via one or more respective electrodes connectable to the electrode interface; a display device; and a processing facility configured to generate a user interface screen based at least in part on the received one or more electrocardiogram signals and to cause display of the user interface screen on the display device, wherein generating and causing display of the user interface screen comprises; generating, from the one or more electrocardiogram signals, one or more electrocardiograms for one or more respective leads; converting the one or more electrocardiograms by time-frequency transform into one or more corresponding two-dimensional time-frequency maps; generating a user interface displaying, for at least one of the one or more electrocardiograms, at least a portion of the electrocardiogram and, in temporal alignment therewith, a temporally coextensive portion of the corresponding time-frequency map. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)

30. One or more computer-readable media storing instructions for processing one or more electrocardiograms associated with one or more respective leads, the instructions, when executed by one or more computer processors, causing the one or more processors to:
-
convert the one or more electrocardiograms by time-frequency transform into one or more corresponding two-dimensional time-frequency maps; and generate a user interface displaying, for at least one of the one or more electrocardiograms, at least a portion of the electrocardiogram and, in temporal alignment therewith, a temporally coextensive portion of the corresponding time-frequency map.
