摘要：
Electrode displacement can be detected using a thoracic impedance or conductivity signal. The thoracic impedance or conductivity signal can be filtered to attenuate cardiac contraction (stroke) and respiration components. A fluid status component of the thoracic impedance or conductivity signal can be used to detect a posture-shift related electrode displacement, such as can result from left ventricular/coronary sinus (LV/CS) lead pullback upon a recumbent to upright posture shift.
