Abstract
This disclosure relates to bioelectric signal detecting circuits, lead wire detecting circuits and medical devices. The lead wire detecting circuit may include a reference voltage generator, at least one comparator, and a logic control module, wherein input ends of the comparator are connected to an output end of the reference voltage generator and an signal output end of a lead wire, respectively, for inputting a reference voltage and a lead signal, and the comparator compares the lead signal with the reference voltage and changes an output voltage at an output end of the comparator according to a comparison result; wherein an input end of the logic control module is connected to the output end of the comparator, and the logic control module determines whether the lead wire is in a connected state or disconnected state by the output voltage at the output end of the comparator.
