System for Determination and Utilization of Cardiac Electrical Asynchrony Data

A system for determination and utilization of cardiac electrical asynchrony data, comprising:

• an analysis circuitry comprising a processor and a memory, the processor configured to execute computer-executable code stored in the memory, the analysis circuitry configured to:
• obtain a plurality of sets of cardiac signals collected in at least two locations of a heart of a patient, the signals comprising at least one of surface electrocardiography signals and pseudo-surface ECG signals;
• detect one or more QRS complexes for each of the sets based on the cardiac signals for that set;
• obtain one or more cross-correlation signals, each of the cross-correlation signals being between at least two of the signal sets and being obtained using the detected QRS complexes from the at least two signal sets;
• and
• calculate one or more asynchrony indices using one or more of the cross-correlation signals, each of the asynchrony indices being indicative of a level of asynchrony between the at least two locations.
