摘要：
Apparatus, consisting of a catheter that is configuredto be inserted into a chamber of a heart and that has oneor more electrodes configured to contact myocardial tissueAt multiple locations in the chamber. The one or moreelectrodes receive electrical signals responsive to aconduction wave traveling through the tissue. The apparatusincludes a display and a processor that is configured toreceive the electrical signals from the catheter and torender to the display, responsively to the electricalsignals, a map of the chamber including an indication oflocal times of occurrence of the conduction wave at themultiple locations. The processor is also configured tocalculate, responsively to the local times of occurrence,a velocity of the conduction wave between the locations andto mark on the map one or more areas of the chamber inwhich the velocity is below a preset threshold.
