Ambulatory electrocardiographic (AECG) monitoring is an essential tool in the diagnostic evaluation of patients with cardiac arrhythmias. Recent advances in solid-state technology have improved the quality of the ECG signals and new dedicated algorithms have expanded the clinical application of software-based AECG analysis systems. These advances, in addition to the availability of inexpensive large storage capacities, and very long-term continuous high-quality AECG monitoring, have opened new potential uses for AECG. New digital recorders have the capability of multichannel simultaneous recordings (from 3 to 12 leads) and for telemetred signal transduction. These possibilities will expand the traditional uses of AECG for arrhythmia detection, as arrhythmia monitoring to assess drug and device efficacies has been further defined by new studies. The analysis of transient ST-segment deviation still remains controversial, but considerably more data are now available, especially about the prognostic value of detecting asymptomatic ischaemia. Heart rate variability analysis has shown promise for predicting mortality rates in cardiac patients at high risk. We review recent advances in this field of non-invasive cardiac testing.
动态心电图（AECG）监测是心律失常患者诊断评估中的一项重要工具。固态技术的最新进展提高了心电图信号的质量，新的专用算法扩展了基于软件的AECG分析系统的临床应用。这些进展，再加上廉价大容量存储的可用性以及非常长期的连续高质量AECG监测，为AECG开辟了新的潜在用途。新型数字记录器具备多通道同步记录（3至12导联）和遥测信号转导的能力。这些可能性将扩展AECG在心律失常检测方面的传统用途，因为新的研究进一步明确了将心律失常监测用于评估药物和器械疗效。对短暂性ST段偏移的分析仍存在争议，但现在有了更多的数据，特别是关于检测无症状性缺血的预后价值。心率变异性分析已显示出预测高危心脏病患者死亡率的前景。我们综述了这一非侵入性心脏检测领域的最新进展。
