The Use of Quadripolar Left Ventricular Leads Improves the Hemodynamic Response to Cardiac Resynchronization Therapy

Background The objective of the present study was to evaluate the usefulness of a left ventricle (LV) quadripolar lead in improving the hemodynamic response to cardiac resynchronization therapy (CRT). Methods and Results We included 27 consecutive patients implanted with a CRT device with an LV quadripolar lead. Hemodynamic parameters were evaluated at 3‐month follow‐up by using impedance cardiography. We assessed the highest cardiac output and...
