摘要： The present invention relates to an apparatus and a method for detecting leads off in a multi-electrode medical diagnostic system. The multi-electrode medical diagnostic system comprises: a carrier circuit unit connected to a plurality of active electrodes and a reference electrode connected to a patient to be detected for generating a plurality of carrier signals of lead impedances and impedance pneumography; a pre-stage protecting circuit coupled to the carrier circuit unit and generating a plurality of input impedance signals to prevent the apparatus from being damaged by defibrillation; and a leads-off detection unit coupled to the carrier circuit unit for demodulating the plurality of input impedance signals into lead impedance related voltages. This present invention further comprises a central processing unit and an analog-to-digital converter for receiving the output of the leads-off detection unit, and calculating the amount and the position of the leads-off, depending on an algorithm embedded in the central processing unit.
