Precordial ST segment maps are currently recorded using a 35 electrode blanket connected to an electrocardiograph through a switch box. Problems in adjustment to patients' chests and artifacts are frequently encountered. Other techniques using a single suction electrode placed on different reference points are time wasting. The authors suggest the use of 35 self-adhesive electrodes (3M "Red Dot" chloride free gel pediatric electrodes--cat N. 2243) connected by a press button to a multichannel EKG recorder. This technique prevents artifacts, assures constant arrangement of the electrodes, is suitable for different thoracic structures and does not need any additional device. The authors consider that such a practical method should make precordial ST mapping a more widespread clinical procedure.
目前，心前区ST段图是通过一个35电极的毯子记录的，该毯子通过一个开关盒连接到心电图仪上。在调整以适应患者胸部时经常会遇到问题和伪影。使用放置在不同参考点的单个吸引电极的其他技术很耗时。作者建议使用35个自粘电极（3M“红点”无氯化物凝胶儿科电极——型号2243），通过按钮连接到多通道心电图记录仪。这种技术可防止伪影，确保电极的恒定排列，适用于不同的胸廓结构，并且不需要任何额外的设备。作者认为，这样一种实用的方法应使心前区ST段映射成为一种更广泛应用的临床操作。
