Early experience with a J-shaped lead inserted transvenously into the right atrial appendage is reviewed in thirty-one patients. Fifteen patients are still being followed with satisfactory atrial programmed pacing for five to ten years. A dislodgement rate of twenty percent led to the development of the "tined" J lead in the hope that better fixation would be achieved. Experimental data has shown the new lead to be stable with evidence in both animal and man of firm fixation of the lead in the appendage. The lead has been inserted in twenty patients. Of these, fifteen are still being followed with satisfactory atrial programmed pacing. There has been no case of dislodgement of the lead in a follow-up period of two years and eight months.
回顾了31例经静脉将J形电极插入右心耳的早期经验。15例患者仍在接受随访，心房程控起搏效果良好，随访时间为5至10年。20%的电极脱位率促使了“带齿”J形电极的研发，以期实现更好的固定。实验数据表明，这种新型电极很稳定，在动物和人体中均有证据显示电极在右心耳中固定牢固。已对20例患者植入了该电极。其中，15例仍在接受随访，心房程控起搏效果良好。在两年零八个月的随访期内，没有出现电极脱位的情况。
