[How much do we understand about pharmacotherapy of cardiac arrhythmias?]

By an anonymous, multiple-choice questionnaire assessed was the knowledge of cardiac electrophysiology and mechanism of action of some antiarrhythmic drugs among the staff members of a department of medicine from a large regional hospital. The overall results were disappointing (over 55 per cent of inaccurate answers), but improved after 3 months (less than 30 per cent). It is concluded that such a polling increases the level of awareness about target problem (cardiac arrhythmia management in the actual case) and improves the performance of health professionals.
