Varying Arrhythmias during Single Hospital Stay in a Case of Systemic Lupus Erythematosus.

Cardiac involvement is present in more than half of the patients with systemic lupus erythematosus (SLE). However, studies on the prevalence of arrhythmias in this disease and laboratorial correlations predictive of their development do not exist. Possible pathophysiological mechanisms include autoimmune process, atherosclerosis and adverse effects of the drugs especially chloroquine used for treatment of this disorder. We present a unusual case of SLE with varying arrhythmias during a single hospital stay.
