Rapidly progressive cardiac sarcoidosis: Initial presentation with sinus node dysfunction and right bundle branch block☆
نویسندگان
چکیده
Introduction Complete heart block is the most common electrocardiogram (ECG) finding in patients with cardiac sarcoidosis because of the predilection of granulomatous infiltration of the basal septum or involvement of the atrioventricular nodal artery. We report a cardiac sarcoid case presenting with sinus node dysfunction and describe the utility of fluorine-18fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET-CT) scans in making the initial diagnosis.

Heart block: a primary manifestation of sarcoidosis.
We present the case of a 55-year-old male who presented with symptoms of dyspnoea and pre-syncope. A 12 lead electrocardiogram demonstrated extensive conduction abnormalities with 2:1 heart block, right bundle branch block and a small Q wave in lead V(1.) This indicated significant myocardial and septal involvement. Echocardiography confirmed the presence of right ventricular infiltration and d...
متن کاملDetection of covert myocardial sarcoidosis by scalene node biopsy.
The antemortem diagnosis of myocardial sarcoidosis is rare in patients without overt signs of the disease. Two patients are presented to alert physicians to the value of early scalene node biopsy when sarcoidosis could be the cause of marked disturbances in cardiac conduction. The first patient, aged 29 years, had first, second, and third degree atrioventricular block and intermittent left and ...

To facilitate the explanation of Fig. 1, the QRS complexes are labelled. The first two show a normal QRS preceded by a normal PR interval. Thereafter the QRS configuration changes. Complexes 3 to 6 show gradual widening, a frontal axis shift to horizontal and loss of the initial q in leads I and V6, an rS pattern in lead III, and the development of a left bundle branch block-like QRS configurat...
متن کاملCardiac conduction in patients with symptomatic sinus node disease.
Cardiac conduction was investigated at the time of pacemaker insertion in 15 patients with symptomatic sinus node disease. Techniques included recording of His bundle potentials, atrial pacing at various heart rates, and atropine administration. Atrioventricular (AV) conduction was impaired in eight patients who manifested one or more of the following: P-R prolongation, P-H prolongation, and de...
