1. An electrical sensing and pacing device comprising:
a balloon catheter;
a first layer connected to or embedded in said balloon catheter, said first layer having an electrode array with a plurality of electrodes configured to or adapted to be positioned on the atrioventricular junction or His bundle anatomical area, wherein the electrode array determines electrical His bundle activation with high spatial and temporal resolution, said first layer having a first top polymer film layer with openings, the plurality of electrodes positioned in the openings, and a first bottom polymer film layer; and
a second layer connected to or embedded in said balloon catheter, said second layer having a pressure sensor array with a plurality of pressure sensors, said second layer having a second silicon layer with cavities, the plurality of pressure sensors positioned in the cavities, and a second bottom polymer film layer.
