Abstract
Cardiac electrograms are recorded in a plurality of channels. Beats are classified automatically into respective classifications according to a resemblance of the morphologic characteristics of the beats to members of a set of templates. Respective electroanatomic maps of the heart are generated from the classified beats.
Claims21
A method, comprising the steps of:
- recording electrograms of a heart of a living subject in a plurality of channels, the electrograms comprising a plurality of beats having morphologic characteristics;
- automatically placing the beats into respective classifications according to a resemblance of the morphologic characteristics of the beats to members of a set of templates;
- and
- generating multiple electroanatomic maps of the heart from the beats in the respective classifications.
An apparatus comprising:
- a probe having a plurality of electrodes on a distal portion thereof;
- electrical circuitry for recording respective time-varying electrograms from the electrodes when the probe is at a location in a heart of a living subject;
- a memory for storing the electrograms;
- a display;
- and
- a processor connected to the memory and operative for performing the steps of:
- recording the electrograms in a plurality of channels, the electrograms comprising a plurality of beats having morphologic characteristics;
- automatically placing the beats into respective classifications according to a resemblance of the morphologic characteristics of the beats to members of a set of templates;
- and
- generating multiple electroanatomic maps of the heart from the beats in the respective classifications;
- and
- presenting the maps on the display.
A computer software product, including a non-transitory computer-readable storage medium in which computer program instructions are stored, which instructions, when executed by a computer, cause the computer to perform the steps of:
- accepting electrograms of a heart of a living subject in a plurality of channels, the electrograms comprising a plurality of beats having morphologic characteristics;
- automatically placing the beats into respective classifications according to a resemblance of the morphologic characteristics of the beats to members of a set of templates;
- and
- generating multiple electroanatomic maps of the heart from the beats in the respective classifications.
