Cardiac conduction system evaluation

A method comprising:

• monitoring intrinsic electrical activity of the patient using a plurality of external electrodes disposed proximate a patient's skin;
• generating a plurality of cardiac breakthrough maps based on the monitored intrinsic activity over a time period, wherein each cardiac breakthrough map is a spatial representation of electrocardiographic potential;
• and
• determining a cardiac conduction system block location based on the plurality of generated cardiac breakthrough maps.

A system comprising:
