Cardiologists are in charge of the follow-up of patients equipped with pacemakers and defibrillators. In many situations, however, the non-specialist will have to take care of these patients. It is therefore essential that the practitioner understands the basics of how these devices work, the potential complications and the situations in which the cardiologist's intervention is necessary. This article summarizes implantation techniques, post-operative follow-up and potential complications of implantable devices. It recapitulates the differences between pacemaker, defibrillator and resynchronization therapy. It explains the stimulation modes and reminds the reader how the magnet works and the precautions to be taken in the operating theatre, during magnetic resonance imaging or in situations of emergency., Competing Interests: Les auteurs n’ont déclaré aucun conflit d’intérêts en relation avec cet article.

Cardiac rehabilitation is associated with a reduced risk of recurrence and mortality after an acute coronary syndrome. Cardiac rehabilitation is a multidisciplinary approach which starts during the acute hospital phase, then followed by a four to six weeks home-based or stationary program, in order to maintain long-term lifestyle changes. Despite the important health benefits of cardiac rehabilitation and its cost-effectiveness, only half of the patients in Europe will achieve a cardiovascular prevention program after an acute coronary syndrome. In the French part of Switzerland, one explanation for this low adherence might be the lack of both stationary and home-based program facilities.

Electrically assisted bicycles (EAB) are flourishing in cities throughout the world and capitalize on ecological and practical advantages, helping in the fight against pollution, CO2 emissions and traffic jam. Human power is necessary to activate the electrical support, so that it equals to a moderate intensity physical activity (> 3 MET), or a vigorous one on hilly courses (>6 MET). The ecological benefits are obvious and transportation departments tend to support citizens who purchase one. EAB offer increased mobility at speeds of 15 to 25 km/h depending on hills and fitness of the rider, but could cause more accidents. EAB is linked to a real physical activity beneficial for health, but potentially more dangerous than a traditional bicycle.
