右心室梗塞(RVMI)时的血液动力学改变,不同于左室梗塞,且治疗亦有差异。因此,早期识别和及时处理RVMI很重要。但在常规12导联心电图上,无RVMI的定位特征,又因右室壁薄,电势弱,即使发生RVMI,也不易在心电图上显现出来。所以,通过常规心电图得到RVMI的诊断的可能性,是很小的。为了探讨右胸前导联心电图对诊断右室梗塞的临床意义,我们自1986年3月至1987年5月对冠心病监护病房收治的25例急性心肌梗塞患者
Right-ventricular infarction (RVMI) hemodynamic changes, different from the left ventricular infarction, and the treatment is also different. Therefore, early identification and timely treatment of RVMI is very important. However, in the conventional 12-lead ECG, there is no RVMI positioning characteristics, but also because of the thin right ventricular wall, weak potential, even in the event of RVMI, it is not easy to appear on the ECG. Therefore, the possibility of diagnosing RVMI by conventional electrocardiography is small. In order to investigate the clinical significance of right anterior chest lead ECG in the diagnosis of right ventricular infarction, from March 1986 to May 1987, 25 patients with acute myocardial infarction admitted to coronary care unit
