Regression of Fragmented QRS Complex: A Marker of Electrical Reverse Remodeling in Cardiac Resynchronization Therapy
Fragmented QRS (fQRS) marks inhomogeneous activation and asynchronous cardiac contraction. It has been proved that cardiac resynchronization therapy (CRT) could reverse geometrical remodeling as well as correct electrical dyssynchrony. We aimed to investigate whether fQRS changed corresponding to the therapeutic response to CRT.
