Figure 4: Maneuvers to ensure transmission of torque to lead tip for septal penetration during lead body rotation: A, Agilis HisProTM catheter with lead and bypass tool inserted at the hemostasis valve. B, retraction of the stiff stylet to a distance of 9 - 10 cm from the lead pin, would ensure the stylet tip is now proximal to the two 90° deflections formed by the sheath.
