| Abstract | 「要旨」72例の各種心疾患患者において, 右肘静脈より99mTc-pertechnetate 20mCi (1〜3ml) を急速静注し, そのfirst transit time-activity curveをBender型シンチカメラにて測定した. 50あるいは100msec毎に記録した左室関心領域のtime-activity curveより, 左室血液駆出率を測定したが, New York Heart Associationの心機能分類によって対象群を分けた場合に, 次の結果を得た. I群55.3% (21例), II群42.1% (34例), III群29.8% (15例), IV群の2例では18%と40%であった. I, II, III群間の平均値の差は統計的に有意であった. なお20例について左室容積変化の様子を4心拍の平均カウント数から求めたが, I群では, 収縮期に大きな容積減少速度を示し, 拡張期も急速期と緩除期を区別することができたが, III群では, 収縮期容積減少速度の低下と拡張期の2相性変化が区別しにくくなる傾向が見られた. II群は両者の中間であった. |

| Abstract | [Summary] Left ventricular function was studied in 72 cardiac patients using 99mTc-pertechnetate and autofluoroscope system 77. A small volume of 99mTc-pertechnetate (20mCi) was injected into right anticubital vein and flushed consecutively with 20 ml of physiological saline. The count over the left ventricle were recorded at 50 - 100 msec intervals during the first transit of radioisotope through the heart. Left ventricular ejection fraction (LVEF) was obtained from the first transit according Jone's method. The patients were divided into four groups according to the functional classification of New York Heart Association (I : 21 cases, II : 34, III : 15, IV : 2). LVEF was 55.3 per cent in group I, 42.1 in II, 29.8 in III and 18 and 40 in two cases of group IV. The differences of mean values are statistically significant. In twenty cases the change of left ventricular volume pattern was calculated from the average value of peak four beats. The pattern of group I reveals the initial sharp decrease of volume with rapid and slow filling period. In group III the change of volume is small and in some cases the rapid and slow filling were difficult to recognize. The group II showed the mixed pattern of I and III. |
