1. A body implantable system, comprising:

  • a lead system comprising;

    an elongated body suitable for passage into the coronary sinus;

    a thermal sensor located proximal to the distal end of the elongated body, the thermal sensor configured for sensing a coronary sinus blood temperature at a location distal to the coronary sinus ostium when the elongated body is positioned in the coronary sinus; and

    a programmable circuit coupled to the lead system, the programmable circuit configured to determine a hemodynamic state using the sensed coronary sinus blood temperature.
