The tip electrode of the LV lead is the cathode and the proximal electrode of the bipolar RV lead often provides the anode for LV pacing. This arrangement creates a common anode for RV and LV pacing.Once correct lead positioning is confirmed, the lead is affixed to the endocardium either passively with tines (like a grappling hook) or actively via a helical screw located at the tip. The screw at the tip of the pacemaker is extended or retracted by turning the outer end of the lead with the help of a torque device.
