Right ventricular infarction frequently occurs in the setting of infarction of the inferior wall of the left ventricle. Although there are several protective mechanisms that may limit the size of the infarction, right ventricular damage can result in right ventricular failure and cardiogenic shock. ECG manifestations of right ventricular infarction can facilitate the early recognition of this syndrome. The standard 12-lead ECG may provide some evidence of infarction of the right ventricle. ST-segment elevation in right precordial leads, however, is far more reliable in establishing a diagnosis. These leads should be recorded immediately if the standard 12-lead ECG reveals an acute inferior wall MI. Continuous ST-segment monitoring may be useful in the early detection of ongoing right ventricular ischemia. ECG markers can aid in the prompt institution of appropriate treatment. It is clear that early recognition of right ventricular infarction can have important diagnostic and therapeutic implications.
右心室梗死常发生于左心室下壁梗死的情况下。尽管有多种保护机制可限制梗死面积,但右心室损伤可导致右心室衰竭和心源性休克。右心室梗死的心电图表现有助于早期识别该综合征。标准12导联心电图可能提供右心室梗死的一些证据。然而,右胸前导联的ST段抬高在确立诊断方面要可靠得多。如果标准12导联心电图显示急性下壁心肌梗死,应立即记录这些导联。持续ST段监测可能有助于早期发现持续的右心室缺血。心电图标志物有助于及时采取适当治疗措施。显然,早期识别右心室梗死具有重要的诊断和治疗意义。
