The mean cord blood/maternal plasma concentration of DX (16 examples) and ST (7 examples) was 67.6% and 73.9%, respectively.As for the dosage, a correlation was found in both DX plasma concentrations (26 examples) (P<0.001) and ST plasma concentration (12 examples) (P=0.04). There was a correlation tendency between DX plasma concentration and serum creatinine (Scr) (P=0.06), was not a significant correlation between ST plasma concentration and Scr (P=0.18). Furthermore, maternal heart rate related to DX plasma concentration weakly (P=0.09), but did not relate to ST plasma concentration (P=0.51). Treatment of fetus tachycardia made fetal atrial heart rate decreased like log approximation. It is expected to apply for approval of health insurance treatment by analyzing more additional target cases., 研究種目:基盤研究(C); 研究期間:2011~2015; 課題番号:23591607; 研究分野:医療薬剤; 科研費の分科・細目:, application/pdf}, title = {胎児頻脈性不整脈に対する経胎盤的抗不整脈薬投与の薬物血中濃度による評価}, year = {2016}, yomi = {コタケ, タケシ and カツラギ, シンジ and イケダ, トモアキ} }
