Quantification of total ischemic burden can be improved by use of microprocessor-driven, multichannel, digital, ST-monitoring devices. ST deviation recorded during angioplasty provides a patient-specific template for identification of patients at increased risk for coronary events after angiographically successful dilation. In patients with ST-segment elevation, evidence of these ST "fingerprint" patterns are associated with elevated risk for coronary events in the postangioplasty period. Such risk is not seen in patients with ST-segment depression or with no ST changes. The increased monitoring capability afforded with digitized 3- or 12-lead monitoring creates new criteria for what constitutes accurate determination of total ischemic burden.
使用微处理器驱动的多通道数字ST监测设备可改善对总缺血负荷的量化。血管成形术期间记录的ST段偏移可为识别血管造影成功扩张后发生冠状动脉事件风险增加的患者提供特定于患者的模板。在ST段抬高的患者中，这些ST“指纹”模式的证据与血管成形术后冠状动脉事件风险升高相关。在ST段压低或无ST段变化的患者中未见这种风险。数字化3导联或12导联监测提供的增强监测能力为准确确定总缺血负荷构成了新的标准。
