最近的技术进步和已发表的研究表明，需要重新评估心电图（ECG）数据记录和分析的要求。最近的事态发展引起了一些问题。首先，1987年计算机处理了大约5200万张心电图（1975年为400万张），现在使用的数字心电图系统超过15,000台（1975年为85台）。此外，计算机辅助心电图正在从学术医疗中心迅速传播到私人医院，诊所和医生办公室。这种技术传播的一个主要因素是采用微芯片技术的便宜（不到5 000美元）的独立解释车。第二，大量的心电图系统，特别是独立的推车，在放大后立即将数据转换为数字形式并进行数字处理。这种类型的处理，与具有比以前更低的噪声特性的放大器相结合，比传统的线性模拟系统具有更高的分辨率和信噪比。
R ecent technologic advancesand published studies point to the need to reevaluate requirements for recording and analysis of electrocardiographic (ECG) data. Severalissues have arisen from recent developments. First, approximately 52 million ECGs were processed by computer in 1987 (up from 4 million in 1975), and more than 15,000 digital ECGsystems are now in use (up from 85 in 1975). 1 In addition, computer-assisted electrocardiography is spreading rapidly from academic medical centers to private hospitals, clinics, and physicians' offices. A major factor in this diffusion of technology is the introduction of inexpensive (less than $5,000) stand-alone interpretative carts using microchip technology.'Second, a large number of ECG systems, particu-larly stand-alone carts, convert data into digital form immediately after amplification andprocess it digitally. This type of processing, combined with pream-plifiers with lower noise characteristics than those available earlier, permitshigher resolutions and signal-to-noise ratios than conventional linear analog systems.
