[Validity of a teaching method of arrhythmias with a simulating machine (author's transl)]. 
The authors have tested a method of teaching the arrhythmias with a simulating machine.  Two groups of students have been drawn by lot and have set for a first test on their knowledge about dysrythmias.  One group was instructed in a classical way, the second one was instructed with the simulating machine which reproduces the majority of rhythm modifications on electrocardioscopic screen.  At the end of the teaching, a post-test took place, then a last one a month later.  The comparison of the two methods by measuring the residual knowledge enables to prove the interest of using simulating machine to teach disorders of cardiac rhythm.
