Experience with 407 transvenous ventricular finned pacing leads with a sintered porous-surfaced electrode is reported. A low complication rate was encountered: 97% of patients were free from lead-related complications. Four patients (1%) required re-operation: two for lead displacement, one for failure to sense spontaneous ventricular activity and one for exit block. A further patient developed exit block which resolved spontaneously. The vast majority of patients had low chronic stimulation thresholds; for example at six months after implantation, the mean threshold for a group of pacemakers with a pulse duration of 0.5 ms was 1.4 +/- 0.7 V and for another group with a pulse duration of 0.8 ms it was 1.9 +/- 0.7 mA. However, six patients developed a transient high stimulation threshold during the month after implantation, and a high threshold developed in another patient at five months and persisted. Mean acute stimulation and sensing thresholds were satisfactory: 0.7 +/- 0.2 V at 0.5 ms pulse duration and 7.6 +/- 2.4 mV, respectively.
本文报道了407根带有烧结多孔表面电极的经静脉心室鳍状起搏导线的使用经验。并发症发生率较低：97%的患者未出现与导线相关的并发症。4例患者（1%）需要再次手术：2例因导线移位，1例因无法感知自发心室活动，1例因出口阻滞。另有1例患者出现出口阻滞，但自行缓解。绝大多数患者的慢性刺激阈值较低；例如，植入后6个月时，一组脉冲宽度为0.5毫秒的起搏器的平均阈值为1.4±0.7伏，另一组脉冲宽度为0.8毫秒的起搏器的平均阈值为1.9±0.7毫安。然而，6例患者在植入后1个月内出现短暂的高刺激阈值，另1例患者在5个月时出现高阈值并持续存在。平均急性刺激和感知阈值令人满意：脉冲宽度为0.5毫秒时分别为0.7±0.2伏和7.6±2.4毫伏。
