Simulation is a learning method based on experience, which has become increasingly more present in training programs in medicine. Interactive, reflective scenarios or even with the possibility of putting non-technical skills or technical resources into practice, from diagnosis to treatment, make simulation an expanding tool. The Spanish Society of Cardiology has included simulation among its training activities, promoting the training of teachers, specific work groups and training programs during the different stages of residents. The organization of this form of learning implies an adequate structuring, for which a correct introduction to the scenario or case (briefing) and, very especially, the subsequent reflective conversation (debriefing) is essential. To objectively evaluate the results of these programs, different scales have been implemented. These scales allow the evaluation of several important aspects, such as previous knowledge, participants’ perception of the activity or even the emotional impact of complex scenarios. Simulation is a growing learning method, with a clear usefulness in the acquisition of both theoretical and, specially, technical, and non-technical skills. It has become evident that simulation has come to stay, and that it will be increasingly used in skills development of future cardiologists in training and other clinical specialties.
