  • Title: [Comparative assessment of the left chest EKG leads V7-V9 and bipolar Slapak and Partilla leads in the diagnosis of posterior and posteriobasal myocardial infarction].

    Abstract:
    The study included 100 patients with acute inferoposterior myocardial infarction consequently admitted to hospital. Both the standard ECG in 12 leads as well as additional V7-V9 and Slapak & Partilla leads were recorded in each patient. Two-dimensional echo at rest was performed to evaluate regional wall motion. The criterion of dividing patients into any MI subgroup was the presence of abnormal Q wave in any system leads. Posterior + inferior MI was found in 88%, limited posterobasal--in 2% and diaphragmal (inferior)--in 10% of patients. Good correlation of Q-wave in II, aVF and S1-S4, V7-V9 and S1-S4 was found. The more abnormal Q waves were revealed in lead systems the more was necrosis size as assessed by echo. We conclude, that additional lead systems are of value in revealing necrosis size and its location in patients with damaged posterior wall.
