作者报道了加拿大温哥华综合医院从1973年9月至1978年2月间,使用CPI厂锂碘电池起搏器的情况。该起搏器脉宽1毫秒,电压5伏,反拗期330毫秒,额定电流30微安,电池容量超过3.5安时。在电流消耗为30微安时,预计寿命为13.98年,保险期为6年。本组250例,男147,女103。平均年龄71.6岁(12～93岁),214例采用心内膜电极,17例心肌电极,19例采用不缝合电极。159例双极电极,91例为单极电极。94例为首次埋藏,156例系更换时植入。共随访3988个病人月,平均15.9月(4～32月)。随访期间9例死亡,原因包括心衰、心肌梗死、脑血管意外、肠系膜上动脉栓塞、心脏停跳。死亡时起搏功能仍正常。仅1例埋入后即时发现起搏失效,在第一周将其更换,经检查系因某电子元件故障以致,R波感知功能失灵所致。创口并发症共12例,其中局部感染2
The authors report the use of CPI lithium-ion battery pacemakers from September 1973 to February 1978 at the Vancouver General Hospital in Canada. The pacemaker pulse width of 1 millisecond, the voltage of 5 volts, anti-stub 330 milliseconds, the rated current of 30 microampere, the battery capacity of more than 3.5 Ah. At a current consumption of 30 microamperes, life expectancy is 13.98 years, with an insurance period of 6 years. The group of 250 cases, male 147, female 103. The mean age was 71.6 years (range, 12-93 years). 214 patients had endocardial electrodes and 17 myocardium electrodes, while 19 patients did not use suture electrodes. 159 bipolar electrodes and 91 monopolar electrodes. 94 cases were buried for the first time, 156 cases were replaced when implanted. A total of 3988 patients were followed up for an average of 15.9 months (4 ~ 32 months). Nine patients died during follow-up. Causes included heart failure, myocardial infarction, cerebrovascular accident, superior mesenteric artery embolization, and cardiac arrest. Pacing at death is still normal. Only one case immediately found embedded pacing failure, in the first week to replace it, due to inspection department due to a failure of electronic components, R wave sensing function failure. A total of 12 wound complications, including local infection 2
