Abstract

A cardiac stimulator has an implantable cardiac lead that carries a temperature sensitive element with a surface thereof in contact with biological matter. The temperature sensitive element emits a temperature signal corresponding to the temperature of biological matter, such as blood, in contact with the surface of the temperature sensitive element. Processing circuitry receives the temperature signal and determines a variability thereof within a selected time interval. A status signal is emitted dependent on this variability.
