One method used to control costs in community cardiovascular disease surveillance is to limit the number of electrocardiograms (ECGs) used to validate acute myocardial infarction (AMI). The Minnesota Heart Survey investigated the impact of decreasing the maximum number of ECGs analyzed on classification of ECG pattern and final AMI diagnosis (definite, probable, none). A 50% sample of all 1980 acute CHD hospital discharge records (ICD-9 code 410 or 411) from 30 of 31 Twin Cities hospitals were abstracted. Comparing results using all available ECGs in the record (maximum of 12) with those obtained using up to 4 ECGs showed little differences in the ECG classification or final AMI diagnosis.
社区心血管疾病监测中用于控制成本的一种方法是限制用于验证急性心肌梗死（AMI）的心电图（ECG）数量。明尼苏达心脏调查研究了减少分析的ECG最大数量对ECG模式分类和最终AMI诊断（明确、可能、无）的影响。从31家双城医院中的30家抽取了1980年所有急性冠心病医院出院记录（ICD-9代码410或411）的50%样本。将使用记录中所有可用ECG（最多12份）的结果与使用最多4份ECG获得的结果进行比较，结果显示ECG分类或最终AMI诊断几乎没有差异。
