Abstract
Methods for treating cardiac complex rhythm disorder in a patient can include receiving a plurality of electrical signals from a sensor system, wherein each electrical signal corresponds with a separate location on a cardiac wall of the heart of the patient, and wherein each electrical signal comprises an electrogram waveform; and ranking the electrical signals relative to each other based on at least a uniformity and a frequency of the electrogram waveform of each electrical signal.
Claims20
A method of treating cardiac complex rhythm disorder in a patient, the method comprising:
- receiving an electrical base signal of a heart comprising a base signal frequency and a base signal waveform;
- simultaneously positioning a sensor system inside the heart of a patient while receiving a plurality of electrical signals from the sensor system, wherein positioning comprises identifying a source of repetitive aberrant electrical activity in the plurality of electrical signals and placing the sensor system such that the source is within a sensing region, wherein the sensing region is defined by a plurality of sensor locations that are in contact with a cardiac wall of the heart, wherein each electrical signal is detected at each of the plurality of sensor locations for at least one heartbeat, and wherein each electrical signal comprises an electrogram waveform;
- determining that the source of repetitive aberrant electrical activity is propagating in an outward direction from within the sensing region based on at least a timing and a frequency of the electrogram waveform of each electrical signal that is distinguishable from the base signal frequency, wherein the sensor system is positioned at a location where the source of repetitive aberrant electrical activity is disposed between a plurality of sensor locations in at least two different directions;
- and
- electrically isolating the source of repetitive aberrant electrical activity by relocating the sensor system and performing at least one focal ablation procedure inside the sensing region.
