Sinus node is the natural pacemaker of the heart which gives out regular electrical pulses to produce each heartbeat. Occasionally there could be an irregular rhythm originating from the upper chambers of the heart known as atrial fibrillation. When it is diseased, this function is defective and called sick sinus syndrome.
