In this table we reported procedural data as functionality parameters of devices leads (left ventricle, right atrium, and right ventricle leads), and procedural times at implant (shin to skin time, fluoro time, CS target vessel, and CS cannulation time) comparing multipolar vs bipolar group of patients. Impedance thresholds are expressed in Ohm. Pacing thresholds are expressed in millivolts for milliseconds. Sensing thresholds are expressed in millivolts. Procedural times (skin to skin time, fluoro time, and CS cannulation time) are expressed in minutes. The “n.s” was for statistical not significant (p value >0.05)
