    • A system including a sensor interface coupled to a processor. The sensor interface is configured to receive and process an analog electrocardiogram signal of a subject and provide a digitized electrocardiogram signal sampled over a first time period and a second time period that is subsequent to the first time period. The processor is configured to receive the digitized electrocardiogram signal, to analyze a frequency domain transform of the digitized electrocardiogram signal sampled over the first and second time periods and determine first and second metrics indicative of metabolic state of a myocardium of the subject during the first and second time periods, respectively, to compare the first and second metrics to determine whether the metabolic state of the myocardium of the subject is improving, and to indicate administration of an intervention to the subject in response to a determination that the metabolic state is not improving.
    • 一种包括耦合到处理器的传感器接口的系统。 传感器接口被配置为接收和处理被摄体的模拟心电图信号,并提供在第一时间段和第一时间段之后的第二时间段中采样的数字化心电图信号。 处理器被配置为接收数字化的心电图信号,以分析在第一和第二时间段采样的数字化心电图信号的频域变换,并且确定指示在第一和第二时间段期间受试者的心肌的代谢状态的第一和第二指标, 第二时间段,以比较第一和第二指标,以确定受试者的心肌的代谢状态是否正在改善,并且响应于确定代谢状态未改善而指示对受试者的干预的施用 。
