In this article, the modified 12-lead system and the bipolar lead systems are discussed, both of which may provide adequate sensitivity and specificity of stress tests for clinical purposes. A single lead V5 or, preferably, bipolar modification of lead V5 may be adequate in certain situations in which cost or the type of population being tested legitimizes such a choice. However, the modified 12-lead system is far more popular for the diagnosis and follow-up of patients with ischemic heart disease. The final choice of lead system for monitoring stress tests will ultimately depend on the needs and resources of a given laboratory.
本文讨论了改良的12导联系统和双极导联系统，这两种系统都可为临床目的提供足够的负荷试验敏感性和特异性。在某些因成本或受检人群类型而使这种选择合理的情况下，单导联V5或者更优选地，V5导联的双极改良导联可能就足够了。然而，改良的12导联系统在缺血性心脏病患者的诊断和随访中更为常用。用于监测负荷试验的导联系统的最终选择将最终取决于特定实验室的需求和资源。
