“…Nevertheless, in a larger multicentre, randomized study, the Atrial Septal Pacing Efficacy Clinical trial (ASPECT), 17 septal pacing did not diminish AF frequency or burden in spite of reducing PACs. 14 These results were confirmed by Hakacova et al 18 that did not find a significant difference in the number of AF episodes and the duration of AF between septal vs. high atrial pacing group. Katsivas et al 19 in a randomized controlled study showed that atrial septal pacing does not prevent AF episodes in patients requiring atrial pacing for sinus node dysfunction when AF episodes are not documented in the 3 months before pacing.…”

“…20-22 IAS-P was shown [4][5][6][7] to have a beneficial effect of reducing AF compared with RAA-P. However, other studies [8][9][10] failed to show such a beneficial effect. IAS-P is a potential treatment to prevent AF but further study should be conducted.…”

“…A trend toward increased use of active-fixation screw-in leads may be because of the following advantages: rapid implantation; low dislodgement rate; easy extraction; and ability to select any pacing site. [3][4][5][6][7][8][9][10][11][12] Using active-fixation screw-in leads, Bachmann bundle pacing could decrease the dispersion of atrial refractoriness and may lead to reduction in the incidence of atrial fibrillation. 8) If trans venous implantation via persistent left superior vena cava is intended, it is recommended to use active-fixation screw-in leads with a sufficient length so that a loop in the right atrium can be formed with appropriate fixation to the right ventricle.…”

Rapid Improvement and Long-term Stability of Pacing Threshold with Active-fixation Screw-in Lead

Background: Active-fixation screw-in leads are associated with initially high thresholds. However, pacing thresholds have been shown to improve within several minutes after screwin. The aim of this study is to investigate the long-term stability of rapidly improved pacing thresholds following the implantation of active-fixation screw-in leads.Methods: We performed a prospective observational study on 68 consecutive patients, who were referred for an initial pacemaker or implantable cardioverter defibrillator implantation. Pacing thresholds, sensing amplitudes, and lead impedances were measured immediately after screw-in. If the initial pacing threshold was higher than 2.0 volts, lead reposition was performed. If the initial pacing threshold was lower than 1.0 volts, the lead position was considered adequate. If the initial pacing threshold was slightly high, i.e., between 1.0 and 2.0 volts, all parameters were measured again 5 minutes after screw-in without lead repositioning, and 1 week, 1 month, 6 months, and 1 year after the procedure.Results: Fifty-three atrial leads and 59 ventricular leads were implanted using activefixation screw-in leads. The initial pacing threshold was slightly high, i.e., between 1.0 and 2.0 volts in 16 (30%) atrial leads and 28 (47%) ventricular leads. Pacing thresholds significantly improved after 5 minutes in both atrial and ventricular leads as follows: 1:5 AE 0:2 to 0:9 AE 0:3 volts (p < 0:05) in atrial leads and 1:5 AE 0:3 to 0:9 AE 0:3 volts (p < 0:05) in ventricular leads. These improved pacing thresholds remained stable during the first year and were 0:8 AE 0:3 volts in atrial leads and 0:8 AE 0:2 volts in ventricular leads after the initial year. P-and R-wave amplitudes did not change significantly during the follow-up. Lead impedances decreased 1 week after the procedure and remained stable in both atrial and ventricular leads.Conclusions: Slightly high pacing thresholds using active-fixation screw-in leads improved rapidly and remained stable in the long term. An acute pacing threshold of <2:0 volts immediately after screw-in may change to an acceptable value without lead repositioning. (J Arrhythmia 2010; 26: 244-249)

Septal atrial pacing for the prevention of atrial fibrillation

Abstract: Implantation of an atrial-active fixation lead on the atrial septum is safe and feasible. However, this study showed no significant difference between septal pacing and high atrial pacing, using the endpoints of AF duration and number of AF episodes.
