Abstract: A system for providing an indication of at least LVD (Left Ventricular Dysfunction) including at least one temperature sensor providing an output indication based on skin temperature at at least one location on a person at a plurality of given times, at least one body activity sensor providing an output indication of at least termination of body activity, a time/temperature ascertainer operative to receive inputs from the at least one temperature sensor and from the at least one body activity sensor to provide output indications of the skin temperature at termination of body activity and thereafter and a correlator operative to correlate the output indications of the skin temperature at termination of body activity and thereafter with established clinical data relating changes in skin temperature at termination of body activity and thereafter to existence of at least LVD, the correlator providing at least an output indication of at least LVD.
