Usefulness of a "Push Technique" for Atrial Lead Implantation
Korean Circulation Journal
and Objectives Dual-chamber pacing is commonly used as a pacing mode maintaining atrioventricular synchrony. However, traditional technique for atrial J lead implantation is relatively timeconsuming and not easy to get optimal sites for both atrial and ventricular leads, especially for lessexperienced operators. We developed a new push technique for atrial J lead implantation. Materials and Method This study included sixty-two consecutive patients 26 males 36 females, 55 10 years, 56 patients
... ears, 56 patients received DDD and 6 received AAI pacemakers from Jan. 1992 through Dec. 1996. Atrial J leads were implanted using a push technique , that is, simply advancing a straightened lead while holding the stylet in the pacing lead at the junction of the superior vena cava and the right atrium. We evaluated the early and long-term result of atrial J lead implantation by the push technique . Results 1 Atrial leads were successfully inserted by the first or second trial of the push technique in the 62 patients 100% . The sensed P wave amplitude was 3.1 1.0 mV, pacing threshold 0.6 0.2 V at the pulse width of 0.5 ms, impedance 547.4 118.5 ohms at 5 V. 2 During follow-up of 28.1 15.7 months, significant changes in the pacing parameters and the dislodgement of atrial leads were not seen. Conclusion The early and long-term result of atrial J lead implantation by the push technique was excellent. This push technique can be used as an easy alternative technique for atrial J lead implantation.
