Patent ID: 7883470

Claim:
An external system for communicating with an implantable system sensing an accelerometer signal indicative of heart sounds and cardiac electrical signals indicative electrical cardiac events, the external system comprising: an external device communicatively coupled to the implantable system, the external device including: an interface circuit configured to communicate with the implantable system; a control circuit, coupled to the interface circuit, configured to receive data representing the heart sounds and the cardiac electrical signals telemetered from the implantable system, detect the heart sounds and the electrical cardiac events from the received data, and calculate timing differences each between a heart sound of the detected heart sounds and an electrical cardiac event of the detected electrical cardiac events; 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; 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; and the calculated timing differences.
