One hundred and twenty-six patients were implanted cardiac devices (pulse generator and implantable cardioverter defibrillator) using passive-fixation leads. Right ventricle leads were fixed in mid septum in 91 patients, lower septum in 24 and RV apex in 11. The reasons why apex was selected were limitation of operation time in 4 patients, limitation of electrical features in 6 and limitation of fixation in 1. Rs pattern of paced QRS was seen in 6 of 24 patients who implanted into lower septum. Lower septum under fluoroscopy seemed to contain electrical mid septum. Only one complication, dislodge, was seen after implantation, which was to be noticed more earlier. The another one patient was implanted active-fixation lead because of probable cardiac surgery. When he received aortic valve replacement at one year after implantation, the screw tip was not seen on interventricular septum but on RV anterior wall. Active-fixation lead has long straight tip, it seemed to advance toward RV anterior wall despite of mid septum target. On the other hand, passive-fixation lead has short tip and flexibility. Passive-fixation lead implantation into interventricular septum dose not require special technique or tricky stylet shape, and has good fixation.
