We believe that the permanent femoral implant utilizing the technical modifications described in this article, offers an alternative to epicardial lead placement when the usual upper venous tree access is not available.

In the 75% of patients with moderate or high mobility, there were no DVT cases. The 6.4% DVT incidence was limited to patients with low mobility and was significantly lower than the norm for this procedure. A larger, randomized study is needed to confirm the benefits of the mobility allowed by an active-fixation lead.

mean PreVAB = 29ms4-7ms. In 100% of cases, the automatic PreVAB would have prevented all R wave oversensing in the recorded data sets. Conclusions: An automatic algorithm to set PreVAB using this method appears feasible. Long term human testing should be performed to further demonstrate efficacy of this approach. 198Continuous monitoring of the native atrio-ventricular conduction in a dual chamber device D.
