IMPLANTABLE HEART STIMULATOR FOR MEASURING DYSSYNCHRONY USING IMPEDANCE
摘要
<p>Implantable heart stimulator connectable to an electrode arrangement comprising a pulse generator adapted to deliver stimulation pulses to a heart of a subject; an impedance measurement unit adapted monitor at least one heart chamber of the heart of the subject to measure the impedance in the at least one monitored heart chamber for generating an impedance signal corresponding to the measured impedance. The impedance signal is applied to a processing means where the signal is processed, according to specified criteria, and a fractionation index value is determined represented by the curve length of the impedance signal during a predetermined measurement period. The fractionation index value being a measure of different degrees of mechanical dyssynchrony of the heart.</p>
