Apparatus and method for outputting heart sounds
First Claim
1. A system configured to be coupled to a patient having a heart, comprising:
- an implantable device configured to sense diagnostic information from the heart, the diagnostic information including first data representative of heart sounds of the patient, second data representative of cardiac electrical signals of the patient, and third data representative of activity signals of the patient; and
an external system configured to be communicatively coupled to the implantable device, the external system including;
an interface circuit configured to communicate with the implantable device;
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 one or more of the first, the second, or the third data from the implantable device through the interface circuit, detect the heart sounds using the first data using a first processing path, generate presentation of the heart sounds using a second processing path, and generate the control signals causing the output device to generate outputs representative of one or more of the heart sounds, the cardiac electrical signals, or the activity signals, and to generate timing comparison among the generated outputs,wherein the output device includes a display device configured to generate visual outputs representative of one or more of the heart sounds, the cardiac electrical signals, or the activity signals, and timing comparison among some or all of the heart sounds, the cardiac electrical signals, and the activity 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.
