Apparatus and method for outputting heart sounds
First Claim
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.

Abstract
An apparatus for outputting heart sounds includes an implantable system and an external system. The implantable system includes a sensor for generating sensed signals representing detected heart sounds, an interface circuit and a control circuit for receiving the sensed signals, generating data representing the heart sounds therefrom, and transmitting the data to the external system via the interface circuit. The external system includes an interface circuit for communicating with the implantable system, and a control circuit for receiving the data representing the heart sounds and for generating control signals that cause an output device to generate outputs representing the sounds. The implantable system may also include a sensor(s) for detecting cardiac electrical signals. In this case, outputs representing the cardiac electrical signals are also output.
