- Title
Helical Representation of Atrial Reentry: A Teaching Aid for Electrophysiology.

- Abstract
Loop Diagrams of Reentry. Cardiac clinical electrophysiology is difficult to teach because it requires mental integration of complex information on cardiac activation, which includes tridimensional spatial orientation of the cardiac structures involved and variables such as refractory period, conduction velocity, and cycle length. Commonly used representations of cardiac arrhythmias include snapshot sequences or ladder diagrams. The former lack time dimension, and the latter lack spatial dimension. We propose a schematic tridimensional representation of reentry as a helicoidal shape that is the result of adding a time dimension to a circular representation. This presentation, which also can be called a ‘loop diagram,’ allows better integration of spatial phenomena with recorded electrogram sequences and can help the teaching of basic clinical electrophysiology.
