本文报告我院1974年至1986年7月使用九种心脏起搏器于70例病人进行150次人工心脏起搏的情况,重点是分析117个国产埋藏式起搏器的质量与临床应用结果。 已使用完毕的67个埋藏式起搏器的平均使用寿命为18.06±10.65个月。其中66个为国产起搏器,其使用寿命以YCP—Ⅱ型最长(19.17±12.35个月),但YCP—Ⅱ、YCP—Ⅰ、GXB—2M及AXB—3型共四种国产起搏器间的平均使用寿命无显著差别(p>0.05)。起搏器失效率为53.7％,其中以YCP—Ⅰ型最高,但无统计学意义(x~2值=4.256,p>0.05)。全组共发生30次起搏器故障,占20.4％(不含电源提前耗竭)。 经分析发现,目前国产埋藏式起搏器存在的主要问题是使用寿命短(平均约18个月)、体积大、重而厚、并发症多、故障率高。其原因关键是能源电池问题。因此,在讨论中强调指出:改进电池性能,研先和采用可靠性高、使用寿命长、体积小的锂碘电池或微型锂电池,不仅是起搏器临床应用的当务之急,而且是生物医学工程学工作者面临的重要课题。
This article reports our hospital from 1974 to July 1986 using nine kinds of pacemakers in 70 cases of artificial heart pacing in 150 cases, focusing on the analysis of the quality of 117 domestic pacemaker and clinical application results. The average useful life of the 67 implanted pacemakers that have been used is 18.06 ± 10.65 months. Among them, 66 were domestic pacemakers, and their service life was the longest in YCP-Ⅱ type (19.17 ± 12.35 months). However, a total of four domestic pacemakers of YCP-Ⅱ, YCP-Ⅰ, GXB-2M and AXB-3 There was no significant difference between the average life of the device (p> 0.05). Pacemaker failure rate was 53.7%, of which the highest YCP-Ⅰ type, but not statistically significant (x ~ 2 = 4.256, p> 0.05). A total of 30 times the pacemaker failure occurred in the group, accounting for 20.4% (excluding power depletion in advance). The analysis found that the main problems existing domestic pacemaker is short life (about 18 months on average), bulky, heavy and thick, more complications, high failure rate. The reason is the key energy battery problems. Therefore, it is emphasized during the discussion that improving battery performance, researching and adopting lithium-iodine batteries or miniature lithium batteries with high reliability, long service life and small volume are not only the urgent tasks for clinical application of pacemakers but also the key points of biomedical engineering Learn the important issues facing workers.
