A retrospective study was carried out of 39 cases of posterior m.i. from 8 months to 6 years after acute episode. In each case the diagnostic reliability of the standard derivations of a series of parameters was evaluated (duration of Q D3 and Q aVF, Q.100/R ratio in aVF, R/S ratio in V1 and R V1/R V6) and of the following accessory derivations: De Maria, III P of Pescador (classical and in two personal modifications), dorsal and sternal derivations. It is concluded that in many cases, standard derivations do not enable previous posterior m.i. to be diagnosed. The De Maria and III P of Pescador derivations (with the proposed personal modifications) are advisable. In isolated cases, the sternal derivation may also be very useful.
对39例急性发作后8个月至6年的后壁心肌梗死患者进行了回顾性研究。对每例患者评估了一系列参数的标准导联（Q D3和Q aVF的持续时间、aVF导联的Q.100/R比值、V1导联的R/S比值以及R V1/R V6）以及以下辅助导联的诊断可靠性：德玛丽亚导联、佩斯卡多尔III P导联（经典导联以及两种个人改良导联）、背部导联和胸骨导联。得出的结论是，在许多情况下，标准导联无法诊断既往后壁心肌梗死。德玛丽亚导联和佩斯卡多尔III P导联（采用建议的个人改良导联）是可取的。在个别情况下，胸骨导联也可能非常有用。
