| Abstract | 「要旨」: 完全左脚ブロック患者70例の安静時タリウム心筋シンチグラム所見と心電図所見を対比検討した. 70例中34例 (48.6%) に心筋シンチグラム上集積低下を認め, 明らかな心筋梗塞の既往のある19例全例 (100%), 既往のない51例中16例 (31.4%) に集積低下が存在した. 前壁中隔の集積低下にI誘導のq波, 下後壁の集積低下に下壁誘導のQ波はそれぞれ高度のspecificityを示したが, いずれもsensitivityは不十分であった. 完全左脚ブロック患者には高率に安静時心筋シンチグラム上集積低下がみられ, 付随する他の心電図所見はこれらの推定に役立つと考えられた. |

| Abstract | [Summary] : Complete left bundle branch block (CLBBB) on the electrocardiogram is frequently associated with ischemic or other organic heart diseases. Seventy patients with CLBBB were examined by Thallium-201 scintigraphy at rest and its findings were compared with electrocardiographic findings. Myocardial perfusion defects were found in 34 patients (48.6%) , 17 in antero-septal region, 15 in infero-posterior region, and 2 in both respectively. Not only in 19 patients with previous myocardial infarction (19/19) , but also in patients without previous myocardial infarction (15/61) , myocardial perfusion defects were observed. An initial q or pathologic Q wave in lead I, or initial q or pathologic Q waves in leads I, V5 and V6 were the findings showing high specificity for antero-septal perfusion defects. Pathologic Q waves in III, aVF were the findings showing high specificity for infero-posterior perfusion defects. But the sensitivity of these electrocardiographic findings for myocardial perfusion defects was not so high. Thus, in the patients with CLBBB, abnormal findings in Thallium-201 scintigram at rest were frequently observed, which may suggest the presence of myocardial fibrosis or degeneration. Certain electrocardiographic findings accompanied with CLBBB may be an important clue to diagnose the presence and location of myocardial infarction, degeneration or fibrosis. |
