摘　　要：InSync Sentry双心室植入式心脏复律除颤器中引入了胸内阻抗测定，可以用来早期确定继发于左心力衰竭（HF）的肺水肿。当阻抗指数增加超过预先设定的水平60Q·d时，可以激发一种可闻的报警（OptiVol警报）。本研究拟观察OptiVol警报的临床价值及其对失代偿性HF的预测作用。连续115例接受InSyncSentry双心室植入式心脏复律除颤器的患者（NYHA分级2．8±0．5，左室射血分数26％±8％）入选研究。当出现OptiVol警报时，评估当时的血流动力学状态。Intrathoracic impedance measurement has been introduced in the InSync Sentry biventricular implantable cardioverter-defibrillator and may permit the early identification of pulmonary fluid accumulation secondary to left-sided heart failure（HF） . An audible alarm（the OptiVol alert） can be triggered when the impedance index increases to greater than a predefined level of 60Ω·day. The aim of this study was to evaluate the clinical value of the OptiVol alert and its prediction for decompensated HF. One hundred fifteen consecutive patients（mean New York Heart Association class 2.8±0. 5, mean left ventricular ejection fraction 26±8% ）who received InSync Sentry biventricular implantable cardioverter-defibrillators were included.
