Serial precordial ST-segment ECG mapping with a grid consisting of 49 recording marks made on the anterior thorax of patients with acute anterior transmural myocardial infarction has been applied in the study of usefulness of this technique. It has been found that a pattern of variable devolution of the magnitude of ST-segment elevations is seen in uncomplicated myocardial infarction. Extension of the infarct has been characterized by re-elevation of ST-segments. Beneficial therapeutic interventions have resulted in reduction of the magnitude of ST-segment elevation. However, the technique cannot be applied in patients with inferior transmural myocardial infarction or in patients with functioning pacemakers, bundle branch blocks, or pericarditis. The significance of adherence to strict guidelines in performing ST-segment mapping and the analysis of mapping data in the light of the total clinical picture at the time of recordings is emphasized.
采用由49个记录标记组成的网格对急性前壁透壁性心肌梗死患者前胸进行系列心前区ST段心电图标测，已应用于该技术实用性的研究。研究发现，在无并发症的心肌梗死中可观察到ST段抬高幅度的可变下降模式。梗死扩展的特征是ST段再次抬高。有效的治疗干预使ST段抬高幅度降低。然而，该技术不适用于下壁透壁性心肌梗死患者或有功能性起搏器、束支传导阻滞或心包炎的患者。强调了在进行ST段标测时遵循严格指南以及根据记录时的整体临床情况分析标测数据的重要性。
