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.
