Abstract
Various embodiments include methods for conducting cardiac resynchronization therapy and systems implementing the method. Various embodiments may include generating, using a processing unit, a three-dimensional (3D) activation map showing the propagation of electrical signals through a heart of a patient, identifying a stimulation point on the heart for cardiac resynchronization; generating real-time images of the heart, displaying, on a display unit, the stimulation point on the real-time images as a virtual stimulation point, implanting a pacing device into the patient at the identified stimulation point, such that the pace maker is aligned with the virtual stimulation point in the real-time images, and stimulating the heart using the pacing device.
Claims19
A cardiac resynchronization method, comprising:
- generating and displaying on a display unit a three-dimensional (3D) activation map showing the propagation of electrical signals through a heart of a patient;
- identifying a stimulation point on the heart for cardiac resynchronization;
- displaying a real-time image of the heart on the display unit;
- aligning the display of the real-time image with the display of the 3D activation map on the display unit;
- identifying a first location on the real-time image that corresponds to the stimulation point;
- displaying a virtual activation point on the real-time image at the first location;
- displaying on the real-time image a pacing device as the pacing device is implanted into the patient;
- aligning the pacing device with the virtual stimulation point so that the pacing device is located at the identified stimulation point;
- and
- stimulating the heart at the stimulation point using the pacing device,
- wherein the real-time image comprises one or more images of the heart received from a fluoroscope, a radiography device, or an X-ray computed tomography (CT) device.
A cardiac resynchronization system, comprising:
- a processing unit comprising:
- an activation map generator configured to generate a three-dimensional (3D) activation map of the heart of a patient;
- a synchronicity determination unit configured to calculate ventricle synchronicity of the heart, based on the activation map;
- a stimulation point generator configured to a identify stimulation point on the heart for increasing the synchronicity of the heart;
- and
- an image integrator configured to align the real-time images of the heart with the 3D activation map and add virtual stimulation points to the real-time images, the virtual stimulation points corresponding to the identified stimulation points;
- and
- a display coupled to the processing unit and configured to display the real-time images of the heart and images generated by the image integrator,
- wherein the real-time images comprise images of the heart received from a fluoroscope, a radiography device, or an X-ray computed tomography (CT) device.
