Sinus bradycardia may be caused by hyperthyroidism, whose primary manifestations include cardiac arrhythmias; additional symptoms may include limb weakness, excessive sweating, and increased appetite. However, sinus bradycardia is not exclusively attributable to hyperthyroidism—it may also result from other conditions, such as sick sinus syndrome or increased intracranial pressure.
