Pacemaker and AQUA Institute for Applied Quality Improvement and Research in Health Care GmbH workgroup. A novel and practical method that might facilitate discrimination between patients with apparent L BBB and true LBBB by comparing Q-LV/QRS ratios during intrinsic activation and during RV stimulation is presented.
