“…Simple T-wave changes are the most common electrocardiographic alterations [4]. Excluding non-specific T-wave abnormalities, conduction disturbances are the most common clini cal manifestation of primary cardiac involvement [3], The conduction defect in myocardial sarcoidosis may be transient, although it is more often permanent [1], Partial or complete bundle branch block is characteristic [7], Ventricular arrhythmias are the second most frequent findings in the form of multifocal, premature, ventricular beats [1], Sinus tachycardia is also quite often reported [4,5]. In a patient with proved systemic sarcoidosis, these electrocardiographic findings, over a period of 2 years, make the case quite compatible with F riedberg's statement: 'The diagnosis of cardiac sarcoidosis is suggested by heart failure of obscure origin in a patient proved to have sarcoidosis [2]'.…”
