A device interrogation for a 32-year-old woman with arrhythmogenic right ventricular cardiomyopathy and an implantable cardioverter-defibrillator capable of monitoring intrathoracic impedance demonstrated a dramatic increase in her OptiVol Fluid index levels in the absence of clinical heart failure. The timing of her intrathoracic impedance changes correlated with plasma volume changes during an uneventful pregnancy without cardiovascular complications. The strengths and limitations of intrathoracic impedance are described in the context of the physiology of pregnancy.
对一名32岁患有致心律失常性右室心肌病且植入了可监测胸内阻抗的植入式心脏复律除颤器的女性进行设备问询时发现，在无临床心力衰竭的情况下，其OptiVol液体指数水平显著升高。在一次无心血管并发症的正常妊娠期间，她胸内阻抗变化的时间与血浆容量变化相关。在妊娠生理学的背景下描述了胸内阻抗的优势和局限性。
