Abstract

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.

摘要

在一项随机前瞻性临床试验中，对标准使用的带凸缘尖端电极和带倒刺心内膜电极的早期（30天）脱位率进行了比较。16根带凸缘尖端电极中有4根（25%）在植入后30天内发生脱位，而18根带倒刺电极在30天内均未脱位（p = 0.01）。我们认为，带倒刺电极代表了电极设计的重大改进，在降低早期脱位发生率方面明显优于带凸缘尖端电极。
