It is very useful for the evaluation of acute chest pain, palpitations, syncope, and acute dyspnea, and it is the gold standard for the diagnosis of cardiac arrhythmias, conduction disturbances, preexcitation syndromes, channelopathies, and some aspects of acute ischemic heart disease (IHD). Additionally, it is a fundamental tool to assess the evolution of heart diseases, in particular ischemic diseases, as well as in situations such as electrolyte disorders and drug therapy. It is also useful for epidemiologic studies and for screening and evaluation of athletes.
