Disclaimer: while every attempt has been made to permit the user to conduct
faithful simulations of selected aspects of cardiac electrophysiology, no
the CESLab software has yet been independently reviewed for medical accuracy.
New CESLab 2.8 Features

Support for conducting simulations on rectangular blocks of cells with
Improved accuracy in compound shape modeller.
New cell display modalities, including instantaneous activation wavefront.
VCG simulation using the Frank or McFee lead systems.
Expanded ElectroWorld viewer windows, incorporating VCG distortion
viewer and selectable
Heart dipole graph windows.
Automatically calibrated color keys.
New polyhedron editor facet display modalities.
Optional overlaying of traces in ECG, VCG, heart dipole scope, and heart
Bugs Fixed Since Last Release (2.4b0)
Bug 4: Deflections of lead V1 much greater than those of V6.
Bug 5: Heart dipole displays lack of continuity between adjacent samples.
Bug 11: If cell size is changed after running a simulation, no more
simulations can be run.
Bug 13: If a cardiac cycle is run, and resolution is changed, ECG is
flat on successive
Bug 24: Wilson¹s central terminal is assumed to be always zero in ECG.
Bug 47: Cell set viewer cutaway offset sliders won't allow the user to
thumb all the way
to the end of their range.
Bug 136: User interface does not perform enough validation of user input.
Bug 160: Command-. does not abort the current operation cleanly in all cases.
Bug 177: Need to clear ECG window before beginning each cardiac cycle.
Bug 180: Fencepost deletion sometimes deletes the wrong fencepost when
the two are very
Bug 193: Regional dipole locations are drawn incorrectly after restore
Bug 194: ECG traces are too close together.
Bug 383: Formula for computing ellipsoidal conduction velocities incorrect.
