1. An external system for communicating with an implantable system configured to transmit first data representative of heart sounds and second data representative of cardiac electrical signals to the external system, comprising:

  • an interface circuit configured to communicate with the implantable system;

    an output device configured to generate outputs in response to control signals; and

    a control circuit coupled to the interface circuit and the output device, the control circuit configured to receive the first and the second data from the implantable system through the interface circuit, process the first data using a first processing path configured for machine detection of the heart sounds using the first data and a second processing path configured for presentation of the heart sounds, and generate control signals causing the output device to generate outputs representative of the heart sounds and the cardiac electrical signals.
