MEDICAL DEVICES FOR MAPPING CARDIAC TISSUE

摘要

Medical devices and methods for making and using medical devices are disclosed. An example method may include a method of mapping the electrical activity of a heart. The method may include sensing a plurality of signals with a plurality of electrodes positioned within the heart, determining a dominant frequency of the plurality of signals and generating an alternate signal for each of the plurality of signals corresponding to the dominant frequency. The alternate signals may have a phase-shift corresponding to one of the plurality of signals. The method may also include displaying a characteristic of the alternate signal over time.

1. A method of mapping electrical activity of a heart, the method comprising:
sensing a plurality of signals with a plurality of electrodes positioned within the heart; determining a dominant frequency of the plurality of signals; generating an alternate signal for each of the plurality of signals corresponding to the dominant frequency, wherein each of the alternate signals has a phase-shift corresponding to one of the plurality of signals; and displaying a characteristic of the alternate signal over time.
