Vectorcardiograms and scalar electrocardiograms were recorded in 30 patients before and after aortocoronary saphenous vein bypass surgery to determine whether vectorcardiograms are helpful in making the diagnosis of perioperative transmural infarction. The vectorcardiogram indicated inferior infarction in 2 cases and anterior infarction in 1 case when the diagnosis was not apparent on the electrocardiogram. In the solitary case of anterior infarction diagnosed by the electrocardiogram, anterior infarction was already present on the preoperative vectorcardiogram. The study indicates that the recording of vectorcardiograms before and after aortocoronary bypass surgery facilitates the diagnosis of perioperative anterior and inferior infarction and may reveal perioperative infarction about a previously infarcted area.
对30例患者在主动脉冠状动脉大隐静脉搭桥手术前后记录了向量心电图和标量心电图，以确定向量心电图是否有助于围手术期透壁性心肌梗死的诊断。当心电图诊断不明显时，向量心电图显示2例下壁梗死和1例前壁梗死。在心电图诊断为孤立性前壁梗死的病例中，术前向量心电图已显示前壁梗死。该研究表明，在主动脉冠状动脉搭桥手术前后记录向量心电图有助于围手术期前壁和下壁梗死的诊断，并可能揭示先前梗死区域周围的围手术期梗死情况。
