The analysis accuracy and susceptibility to faults of the additional diagnostic functions were tested in 16 patients (eight men, eight woman, average age 61.5 +/- 10.8 years, 14 VVI, 2 AAI) with diagnostic pacemakers (Quintech DPG 921). The average observation period was 19.7 months. With 109 follow-up intervals of an average duration of 87 +/- 39 days, this meant an observation period of 25.9 patient years. A stage-by-stage test structure over several intervals of time was applied in order to validate the data acquired through pacemaker Holter functions by means of control ECGs and mathematical test methods. The only fault to occur in the diagnostic functions was a loss of stored data. This was observed in 10% of the follow-up intervals and was on the average 28% (16%-38%) of the total events. Forty-four percent (7/16) of the pacemakers were affected by this malfunction. Our results show that the diagnostic data are certainly correctly acquired. The clinical value of the diagnostic functions is clearly reduced by this potential loss of data.
在16例植入诊断性起搏器（Quintech DPG 921）的患者（8名男性，8名女性，平均年龄61.5±10.8岁，14例VVI，2例AAI）中测试了附加诊断功能的分析准确性和故障易感性。平均观察期为19.7个月。共有109个随访间期，平均时长为87±39天，这意味着观察期为25.9患者年。采用分阶段测试结构，跨越几个时间间期，以便通过对照心电图和数学测试方法验证通过起搏器动态心电图功能获取的数据。诊断功能中出现的唯一故障是存储数据丢失。这在10%的随访间隔中观察到，平均占总事件的28%（16%-38%）。44%（7/16）的起搏器受到此故障影响。我们的结果表明，诊断数据肯定能正确获取。这种潜在的数据丢失明显降低了诊断功能的临床价值。
