Abstract
A method for mapping abnormal electrical activity, including obtaining electrical signal data from respective locations in a heart of a living subject, and automatically analyzing the signal data to identify complex fractionated electrograms (CFEs) therein. The method further includes analyzing the CFEs so as to identify reentry locations comprised in the respective locations, and displaying information derived from the identification in relation to a map of the heart.
Claims18
A method for mapping abnormal electrical activity, comprising:
- obtaining electrical signal data from respective locations in a heart of a living subject;
- automatically analyzing the signal data to identify complex fractionated electrograms (CFEs) therein;
- analyzing the CFEs so as to identify reentry locations comprised in the respective locations;
- and
- displaying information derived from the identification in relation to a map of the heart.
Apparatus for mapping abnormal electrical activity, comprising:
- a probe which is configured to receive electrical signal data from respective locations in a heart of a living subject;
- and
- a processor which is configured:
- to automatically analyze the signal data to identify complex fractionated electrograms (CFEs) therein,
- to analyze the CFEs so as to identify reentry locations comprised in the respective locations, and
- to display information derived from the identification in relation to a map of the heart.
A computer software product for mapping electrical activity, including a tangible computer-readable medium in which computer program instructions are stored, which instructions, when read by a computer, cause the computer to:
- receive electrical signal data from respective locations in a heart of a living subject;
- automatically analyze the signal data to identify complex fractionated electrograms (CFEs) therein;
- analyze the CFEs so as to identify reentry locations comprised in the respective locations;
- and
- display information derived from the identification in relation to a map of the heart.
