Abstract

Представлены способ и система для получения оценки по меньшей мере одного кардиального параметра индивидуума. На тело индивидуума накладывают комплект электродов с тем, чтобы приложить к телу электрическое поле и сформировать электрические выходные сигналы, характеризующие изменение систолического импеданса и скорости этого изменения во время сердечного цикла. Предусмотрено также получение дополнительных данных, по меньшей мере, характеризующих следующие параметры или состояние индивидуума: значение полного периферического сопротивления (TPR), значение сердечного индекса (CI) и наличие состояния острой сердечной недостаточности (ОСН). Эти дополнительные данные анализируют, чтобы определить, удовлетворяют ли значение TPR первому заданному условию и/или значение CI второму заданному условию и/или выявлено ли состояние ОСН. С учетом этого определения используют данные, соответствующие измеренным электрическим сигналам, для селективного вычисления по меньшей мере одного кардиального параметра, основываясь на данных об изменении систолического импеданса или на данных о скорости изменения импеданса.
