[Utility of cardiac event recorders in diagnosing arrhythmic etiology of palpitations in patients without structural heart disease].

Objective: To determine the diagnostic yield of transtelephonic event monitors for identifying the reason for palpitations in patients with no structural heart disease.

Patients And Method: For 20 months we enrolled all patients reporting palpitations in whom heart disease had been ruled out by medical history, physical examination, ECG and transthoracic echocardiography. All patients underwent 24 h Holter monitoring, which did not provide diagnostic information.
