1. An external system for communicating to an implantable system sensing an accelerometer signal indicative of heart sounds and cardiac electrical signals indicative electrical cardiac events, the external system comprising:

  • an interface circuit to communicate with the implantable system;

    a control circuit, coupled to the interface circuit, to receive data representing the heart sounds and the cardiac electrical signals from the implantable system; and

    an output device coupled to the control circuit, the output device including a screen display including;

    a plurality of horizontal traces including simultaneously displayed one or more accelerometer traces related to the heart sounds and one or more cardiac electrical signal traces each showing one of the cardiac electrical signals; and

    visual indicia indicative of the heart sounds, the visual indicia displayed in association with locations of the heart sounds on at least one of the displayed one or more accelerometer traces.
