Abstract

Claims (44)

1. A method for treating an arrhythmia of a patient, the method comprising:

under control of one or more computing systems,

accessing seed anatomies of a body part that is a heart, each seed anatomy having a seed value for each of a plurality of anatomical parameters of the body part;

for each of a plurality of seed anatomies of the body part, displaying a seed representation of the body part based on seed values of anatomical parameters of that seed anatomy;

accessing a set of weights that includes a weight for each seed anatomy;

generating a three-dimensional (3D) mesh representing the body part based on a simulated value for each anatomical parameter by, for each anatomical parameter, combining the seed values of the seed anatomies of that anatomical parameter, factoring in the weights of the seed anatomies;

displaying a simulated representation of the body part, the simulated representation derived from the 3D mesh; and

for each of a plurality of electrophysiology parameter specifications that include an arrhythmia source location,

running a simulation based on the 3D mesh to generate modeled electromagnetic output of the body part based on that electrophysiology parameter specification; and

generating a cardiogram based on the modeled electromagnetic output; and

storing the cardiogram in association with the arrhythmia source location of that electrophysiology parameter specification;

receiving a patient cardiogram; and

identifying an arrhythmia source location associated with a generated cardiogram based on similarity between the patient cardiogram and the generated cardiogram; and

performing an ablation on the heart of the patient based on the identified arrhythmia source location.

2. The method of claim 1 wherein the seed representations are displayed in a circular arrangement with the simulated representation displayed within the circular arrangement.

3. The method of claim 2 further comprising, under control of the one or more computing systems, displaying, in association with each displayed seed representation for a seed anatomy, an indication of the weight associated with that seed anatomy.

4. The method of claim 3 further comprising, under control of the one or more computing systems, displaying a line between each displayed seed representation and the displayed simulated representation, wherein the displayed indication of the weight for a seed anatomy is displayed in association with the displayed line between the displayed seed representation for that seed anatomy and the displayed simulated representation.

5. The method of claim 1 further comprising, under control of the one or more computing systems, providing a user interface element for specifying the weight for each seed anatomy.

6. The method of claim 1 further comprising, under control of the one or more computing systems, providing a user interface element for specifying a plurality of sets of weights, with each set including a weight for each seed anatomy.

7. The method of claim 6 wherein the plurality of sets of weights are specified by providing a range of weights and an increment.

8. A method for treating an arrhythmia of a patient, the method comprising:

under control of one or more computing systems,

for each of a plurality of seed anatomies of a heart, displaying a seed representation of the heart based on seed values of anatomical parameters of that seed anatomy; and

displaying a simulated representation of the heart based on a simulated anatomy derived, for each anatomical parameter, from a simulated value for that anatomical parameter generated from a weighted combination of the seed values of the seed anatomies for that anatomical parameter; and

for each of a plurality of electrophysiology parameter specifications that include a source location of a heart disorder,

running a simulation of electrical activity of the heart over time to generate simulated electromagnetic output of the heart having the simulated anatomy and having that electrophysiology parameter specification;

generating derived electromagnetic data from the simulated electromagnetic output; and

storing a mapping of the derived electromagnetic data to that source location;

receiving patient electromagnetic data; and

identifying a source location that is mapped to derived electromagnetic data that is similar to the patient electromagnetic data; and

performing an ablation on the heart of the patient based on the identified source location.

9. The method of claim 8 wherein the seed representations are displayed in a circular arrangement with the simulated representation displayed within the circular arrangement.

10. The method of claim 8 further comprising, under control of the one or more computing systems, displaying, in association with each displayed seed representation for a seed anatomy, an indication of a weight associated with that seed anatomy.

11. A method for treating an arrhythmia of a patient, the method comprising:

under control of one or more computing systems;

generating a three-dimensional (3D) mesh representing a heart based on a value for each of a plurality of anatomical parameters of the heart;

for each of a plurality of electrophysiology parameter specifications that include an arrhythmia source location,

running a simulation based on the 3D mesh to generate modeled electromagnetic output of a heart based on that electrophysiology parameter specification; and

generating a simulated cardiogram based on the modeled electromagnetic output; and

training a neural network using each simulated cardiogram labeled with an arrhythmia source location as training data;

receiving a patient cardiogram collected from the patient;

applying the trained neural network to the patient cardiogram to identify an arrhythmia source location; and

outputting an indication of the identified arrhythmia source location; and

performing an ablation on the heart of the patient based on the identified arrhythmia source location.
