| Abstract | 「要旨」 急性心筋梗塞に合併し, 診断困難であった右室梗塞例 (8例) において, そのRIマルチゲート心プール法にFourier解析を適用し, 位相像, 振幅像およびその位相分布ヒストグラム, 心機能などに関し下・後壁梗塞のみの症例 (16例) と比較検討した. その結果, 右室梗塞合併例では右室における駆出分画の低下, 振幅の欠損〜低下, 位相の遅延, 位相角の標準偏差の増大が著明であり, さらに従来よりの右室局所壁運動異常の検討を加えると, 非侵襲的に下・後梗塞のみの症例と明らかに区別できた. したがって, Fourier解析は右室梗塞の診断向上に有用と考える. |

| Abstract | [Summary] Eight cases of right ventricular infarction were studied, compared with 16 cases of infero-posterior myocardial infarction without RV infarction, using Fourier analysis of biventricular radionuclide gated imaging. The characteristic findings of right ventricular infarction were as follows : 1) RVEF was decreased significantly and the right ventricular wall motion showed a-or dyskinesis and indicated an abnormal contraction sequence in the amplitude scan. 2) By phase analysis for identifying RV wall motion abnormalities, an inverse relationship between RVEF and SD of RV phase histogram was observed. The mean value of RV phase was not correlated with heart rate. In conclusion, Fourier analysis of radionuclide ventriculography may improve the diagnostic sensitivity of right ventricular infarction. |
