[Imaging studies in arrhythmias].

Imaging studies play a very important role in the diagnosis of cardiac arrhythmias. They are able to answer many questions relating to the diagnosis and treatment of patients. Not all types of arrhythmias require you to perform imaging studies. Diagnosis require above all: ventricular tachycardia and supraventricular tachycardia, ventricular extrasystoles requiring treatment, atrialfibrillation, individuals who are at genetically diseases leading to severe arrhythmia, patients before ablation procedures and cardioversion, arrhythmias in athletes and people performing specific professions (eg pilots). The primary non-invasive imaging technique for the diagnosis of arrhythmias is the ECHO, also safe in pregnant women. Other imaging studies should be performed in case of inability to obtain sufficient diagnostic information in ECHO, because of the cost, availability and worse side effects (class of recommendation IIaB by AHA/ACC/ESC). Among these studies is the study of magnetic resonance imaging "gold standard" for assessing the anatomy and function of the heart, allows the assessment of myocardial structure and can significantly supplement the information obtained in the study of ECHO, is also safe in pregnant women.
