Medical devices for mapping cardiac tissue
First Claim
1. A method for mapping the electrical activity of a targeted tissue region in a body, the method comprising:
- receiving a data set corresponding to a plurality of cardiac signals sensed over a period of time;
determining propagation angles for the plurality of signals using the data set, the propagation angles including at least one propagation angle exceeding a threshold level of randomness; and
generating a propagation map including a visual indicator corresponding to the at least one propagation angle exceeding the threshold level of randomness.

Abstract
Medical devices and methods for making and using medical devices are disclosed. An example medical device may include a system for mapping the electrical activity of the heart. The system may include a catheter shaft with a plurality of electrodes. The system may also include a processor. The processor may be capable of collecting a set of signals from at least one of the plurality of electrodes. The set of signals may be collected over a time period. The processor may also be capable of calculating at least one propagation vector from the set of signals, generating a data set from the at least one propagation vector, generating a statistical distribution of the data set and generating a visual representation of the statistical distribution.

11. A non-transitory computer-readable medium comprising executable instructions that, when executed by one or more processors, cause the one or more processors to:
-
receive a data set corresponding to a plurality of cardiac signals sensed by a plurality of electrodes over a period of time; determine propagation angles for the plurality of signals; determine when at least one propagation angle of the propagation angles exceeds a threshold level of randomness; and generate a propagation map including a visual indicator corresponding to the at least one propagation angle. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
