Abstract
The invention provides methods for mapping the electrical activity of the heart and create cycle length maps to guide ablation to treat atrial fibrillation.
Claims20
A method for cycle length mapping, the method comprising:
- recording electrical activity at a location on cardiac tissue as an electrogram;
- identifying a characteristic deflection within the electrogram;
- measuring times from the characteristic deflection to previous characteristic deflections;
- modeling a distribution of the measured times;
- and
- assigning a peak value of the distribution as a cycle length associated with the characteristic deflection at the location on the cardiac tissue.
3 more elements
A system for cycle length mapping, the system comprising:
- a cardiac mapping catheter with an electrode array disposed on a distal portion of the catheter, the electrode array comprising a plurality of electrodes;
- and
- a computer system comprising a processor coupled to a memory subsystem having instructions stored therein executable by the processor to operate the electrode array to record electrical activity at a location on cardiac tissue as an electrogram when the distal portion of the catheter is inserted into a chamber of a heart of a patient, wherein the computer system is further operable to
- identify a characteristic deflection within the electrogram;
- measure times from the characteristic deflection to previous characteristic deflections;
- model a distribution of the measured times;
- and
- assign a peak value of the distribution as a cycle length associated with the characteristic deflection at the location on the cardiac tissue.
