Claim Text:
1. Method for operating a subcutaneous pacemaker, comprising the procedures of: building a database of a cardiac cycle of a patient suffering from bundle branch block, said database comprising time stamped entries indicating an onset of a P wave and a time duration of said P wave of said cardiac cycle and an onset of a QRS complex and a time duration of said QRS complex of said cardiac cycle immediately following said P wave, said database being built using at least two subcutaneous sensors for sensing said onset and said time duration of said P wave and said onset and said time duration of said QRS complex; determining atrioventricular (AV) delays of said cardiac cycle corresponding to measured P-P intervals of said cardiac cycle based on said time duration of said P wave and said onset of said QRS complex, said AV delays being stored in said database; and artificially pacing a first ventricle of said patient suffering from bundle branch block using said pacemaker according to said AV delays in said database, thereby enabling native activation of a second ventricle of said patient not suffering from bundle branch block and thereby also anticipating a correct time during said cardiac cycle to pace said first ventricle to maximize a likelihood of simultaneous activation of said first ventricle and said second ventricle.
