Patent ID: 11931158
Assignee: ST. JUDE MEDICAL, CARDIOLOGY DIVISION, INC.
Field: Medical technology (Instruments)
Classification: CPC A | IPC A

Claim 9:
10. An electroanatomical mapping system, comprising:
a plurality of localization field generators that generate a non-ionizing localization field to measure a location of a multi-electrode catheter within a patient's heart;
a display; and
a cardiac activity mapping processor configured to:
receive a plurality of electrogram signals S(t), wherein each of the plurality of electrogram signals S(t) is measured by the multi-electrode catheter at a respective location within the patient's heart;
associate, with each of the plurality of electrogram signals S(t), the respective location within the patient's heart at which the respective electrogram signal S(t) is measured;
compute a scalogram G(f, t) for each of the plurality of electrogram signals S(t);
compute an energy function L(t) for each scalogram G(f, t);
compute a pulse wave LPulse(t) for each energy function L(t);
compute a metric for each of the electrogram signals S(t) using the respective pulse wave LPulse(t); and
output on the display a graphical representation of the metrics for the plurality of electrogram signals on a graphical representation of a cardiac model, wherein the metric for each of the electrogram signals S(t) is output on the graphical representation of the cardiac model according to the respective location within the patient's heart.
