New permanent endocardial atrial J lead: implantation techniques and clinical performance

The potential benefits of pacing systems which restore A-V synchrony have long been recognized. However, availability of atrial leads which are easily implanted and which consistently perform well has been limited. A new version of the silicone rubber tined J leads is now available. Changes were made in the insulation material, conductor configuration, tine configuration, and a J memory coil was added. After over three years of use in 100 patients, we conclude that these leads are easier to implant than previous atrial leads, and that they demonstrate excellent clinical performance.
