Tined transvenous endocardial electrodes: results of a randomized prospective study

The early (30-day) dislodgment rate of standard-use flange-tipped and of tined endocardial electrodes was compared in a randomized prospective clinical trial. Four of 16 (25%) of the flange-tipped leads and none of the 18 tined leads dislodged within 30 days of implantation (p = 0.01). We believe that the tined electrode represents a major improvement in electrode design and is clearly superior to the flange-tipped electrode in reducing the incidence of early dislodgment.
