| Abstract | 「1. 要旨」心房細動患者のうち心不全群と, 非心不全群についてQD時間(心電図上のQ波より末梢動脈波形の急峻な立ち上がりを示すまでの時間)の計測を行い, 比較検討をした. QD時間は非心不全群では175.4±30.7msec(mean±SD), 心不全群では218.0±62.6msecを得た. RR間隔は非心不全群では0.594±0.128msec, 心不全群では0.689±0.203msecであった. RR間隔は両群で有意差があったものの, 分布域及び最多値の等しい分布であったが, QD時間は両群で有意差が認められ, 200msec以上に延長すると心不全であると判定できた. さらに, 心不全群は非心不全群に比べて, 拡張期圧及び脈圧に対するQD時間の分散が大きくなるのが特徴であった. QD時間は拡張期圧と正の相関を示し, pre-ejecton period(PEP)と同様に, 心筋収縮力を反映すると考えられた. QD時間は脈圧と負の相関を示し, 一回心拍出量とも負の相関を示すと考えられた. |

| Abstract | We deviced a system that measures time of Q wave, times and values of maximum and minimum arterial pressure continuously. 2700 sucessuve ECG recordings and invasive radial arterial pressure recordings obtained from two hospitalized patients with a diagnosis of chronic atrial fibrillation were selected for this study. We analyzed the interactions between QD time (duration from the Q wave of electrcardiogram to the onset of the rapid upstroke of radial arterial pressure) and diastolic pressure and pulse pressure. QD time reflects isovolumic contraction time and contractility, as well as PEP. QD time was inversely correlated with pulse pressure and reflected on diastric pressure. The average and standard deviation of QD time of the patient with heart failure were 218.0 msec and 62.6 msec and those of the patient without heart failure was 175.4 msec and 30.7 msec. QD time of the patient with heart failure was significantly longer than that of the patient without heart failure. It was considered that cardiac performance of the patient with heart failure was less stable and less regular than that without heart failure. |
