Abstract
Apparatus, consisting of a catheter that is configured to be inserted into a chamber of a heart and that has one or more electrodes configured to contact myocardial tissue at multiple locations in the chamber. The one or more electrodes receive electrical signals responsive to a conduction wave traveling through the tissue. The apparatus includes a display and a processor that is configured to receive the electrical signals from the catheter and to render to the display, responsively to the electrical signals, a map of the chamber including an indication of local times of occurrence of the conduction wave at the multiple locations. The processor is also configured to calculate, responsively to the local times of occurrence, a velocity of the conduction wave between the locations and to mark on the map one or more areas of the chamber in which the velocity is below a preset threshold.
