摘　　要：本文通过120例心肌梗塞病人心电图 ptfv_1和 X 线胸片心/胸值与临床心功能及超声心动图(UCG)的对照分析显示:①UCG 心功能参数 EF 与 ptfv_1和心/胸值均呈明显负相关,相关系数分别为-0.72与-0.80(P 均<0.0005);②用 ptfv_1或心/胸值单项指标判断Ⅰ、Ⅱ和>Ⅲ置级心功能时,ptfv_1值分别为<0.02、0.02～0.04及≥0.05mm·s(绝对值);心/胸值分别为<0.5、0.5～0.59及≥0.6。若联合应用 ptfv_1和心/胸值判断各级心功能时,在不同程度上敏感性降低,特异性与预测指数皆增高,尤以判断≥Ⅲ级心功能为明显,其敏感性降低至17%,但特异性与预测指数升至100%。这表明按 ptfv_1≥0.05mm.s(绝对值)和心/胸值≥0.6判断≥Ⅲ级心功能的可靠性大。The present article compared ptfv_1 and cardiac-chest ratio with clinical heart function grade and EF value calculated by untrosound cardiograph(UCG),in 120 patients with myocardial in- farction.The result showed①Negative correlation significant was present when comparing EF value to ptfv_1 and cardiac-chest ratio,correlaton coefficient was-0.72 and-0.80 respectively(P<0.05);② when using ptfv_1 or cardiac-chest ratio alone to judge heart function grade Ⅰ,Ⅱ or≥Ⅲ,ptfv_1 value was(0.02,0.02～0.04 and 0.05mm·s(absolute value)respectively;cardiac-chest ratio was< 0.5,0.5～0.59 and≥0.6 respectively,when ptfv_1 and cardiac-chest ratio were associated to deter- mine heart function grade,to a certain sensitivity was decreased,but specifiaOlity and predicating index were increased;especially when heart function grade≥Ⅲ sensitivity decreased to 17% specifiablity and predicating index all rised up to 100%,indicating that when association of ptfv_1≥ 0.05mm·s (absolute value)and cardiac-chest ratio≥0.6 to judge heart function grade,especially≥grade Ⅲ,relia- bility was more large and more tallied with the actual situation.
