Why the study?
Atrial arrhythmias have not been focused upon as cardiac sarcoidosis-related conditions, despite growing physician awareness.
Physicians should be aware that atrial arrhythmias and atrial involvement are likely more common in cardiac sarcoidosis than previously recognized.
May warrant screening for atrial arrhythmias in cardiac sarcoidosis; leaves open questions on incidence, risk, and management.
Severe ventricular arrhythmias such as high-grade atrioventricular block and ventricular tachycardia may cause lethal conditions or sudden death in patients with cardiac sarcoidosis (CS). Physicians should examine patients carefully for these conditions and treat them appropriately. As arrhythmias are being better diagnosed and treated, physicians are increasingly aware of atrial arrhythmias, which have not been focused upon as CS-related conditions, in patients with CS. This article reports a case of atrial flutter in sarcoidosis, and discusses literature findings on atrial arrhythmias and atrial involvement of CS. It is highly likely that atrial arrhythmia and supraventricular conduction disorder associated with or caused by CS are more common than previously thought. Physicians should pay careful attention for these conditions in the diagnosis and treatment of CS.
