Systems and methods examine heart tissue morphology by locating electrodes in contact with a region of heart tissue to sense the timing of a local depolarization events. From this, the systems and methods derive the propagation velocities of the depolarization events and create an output that displays the derived propagation velocities in spatial relation to sensing electrode. The systems and methods can arrange the derived propagation velocities into groups of equal propagation velocities and generate in three dimensions an output of the groups of equal propagation velocities in spatial relation to the location of the sensing electrodes. The iso-conduction display more rapidly identifies the regions of slow conduction which are candidate ablation sites, than an iso-chronal or iso-delay display.
