When the heart is functioning properly the sinus node controls the firing of action potential that contract the heart. When the sinus node dominates the heart will contract in a synchronized and effective rhythm This is called sinus rhythm.

Atrial fibrillation (afib) is an irregular heart rhythm where the upper chambers of the heart beat chaotically and out of sync with the lower chambers. Sinus rhythm is a normal heart rhythm where the heart beats in a regular, coordinated pattern. Key differences include the irregularity of afib versus the regularity of sinus rhythm, as well as the potential for symptoms and complications associated with afib.
This is an irregular cardiac rhythm due to a variation in the sinus rhythm -- the heartbeat usually increases during inhalation and decreases during exhalation. This condition is common in children and young adults.
