Abstract

Methods and electronic tools for imaging a chest region of a patient and communicating with a heart stimulation device used by the patient are disclosed. The electronic tool may include a communications device for two-way data transmission of signals encoded with information to and from the heart stimulation device. The tool may also include an imaging device for radiating energy onto the chest of the patient and receiving energy as it is reflected from the chest region to produce an image signal. The tool may include a display screen for showing an image of the chest area and/or the information received from the heart stimulation device. The tool may also include a processor for formulating and/or analyzing information sent to and/or received from the heart stimulation device. One method of using the electronic tool includes analyzing the image signal and/or received information to provide instructions to the heart stimulation device.

Claims

1. A method of programming a heart stimulation device of a patient, the method comprising the steps of:

generating, with an imaging device, an image signal representative of an image of an area around the heart;

receiving a first signal transmitted by the heart stimulation device;

analyzing, with a processing device in electrical communication with the imaging device and a communications device, the first signal to measure a response of the heart; and

producing, with the processing device and in response to the measured response, a second signal encoding instructions for varying one or more stimulation parameters of the heart stimulation device.

2. The method of claim 1, further comprising a step of communicating the second signal to the heart stimulation device.

3. The method of claim 1, further comprising a step of displaying a representation of the image signal and a representation of the first signal on a display screen.

4. The method of claim 1, further comprising a step of positioning leads of the heart stimulation device within the heart, wherein the image signal and the response extracted from the first signal indicate the position of the leads, and wherein the instructions encoded by the second signal are based upon the position of the leads.

5. The method of claim 1, comprising altering an atrial-ventricle delay using information generated with the imaging device.

6. The method of claim 1, comprising altering a right ventricle-left ventricle delay using information generated with the imaging device.

7. The method of claim 1, comprising altering a synchronization of a septum-lateral wall displacement using information generated with the imaging device.

8. The method of claim 1, comprising measuring an aortic flow from the image signal.

9. The method of claim 1, comprising measuring a ejection fraction from the image signal.

10. The method of claim 1, comprising measuring a size of the heart of the patient from the image signal.

11. An electronic tool for communicating with an implantable heart electrostimulation device and for imaging a chest region of a patient, the electronic tool comprising:

an imaging device that radiates energy onto the chest region and that detects energy reflected by the chest region to produce an image signal;

a communication device that receives a first signal with encoded information from the heart electrostimulation device; and

at least one processor in electrical communication with the imaging device and the communication device, wherein the at least one processor formulates an instruction for the heart electrostimulation device by analyzing the image signal or by analyzing the information encoded on the first signal.

12. The electronic tool of claim 11, further comprising:

a display screen that is communicatively linked to the imaging device and that displays a representation of the image signal or a representation of the encoded signals.

13. The electronic tool of claim 11, wherein the processor communicates with the imaging device, analyzes the image signal, and formulates a first signal that is sent to the heart electrostimulation device.
