WebWhat Is a Biventricular Pacemaker? Leads are tiny wires implanted through a vein into the right ventricle and into the coronary sinus vein to pace or regulate the left ventricle. Usually (but... WebPacing counters significantly overestimated the amount of effective BiV pacing, which leads to a wrong perception of the therapy success. Since the results, of the MADIT-CRT trial, we have some important insight on the CRT response in different kinds of LBBB morphology [ 15 ].
