Authors' recommendations: Sinus rhythm is the heart's normal rhythm. The electrical impulse that controls heart rhythm and rate is initiated by the sinoatrial (SA) node, the heart's natural pacemaker. The electrical impulse travels in an organized manner through the heart, first across the upper chambers of the heart, the atria, causing them to contract and pump blood to the lower chambers of the heart, the ventricles. In atrial fibrillation (AF), the electrical impulses are not sent to the atria from the SA node. Instead they are sent from ectopic trigger sites and/or the electrical impulses travel through the atria in an erratic and circular manner in abnormal pathways known as re-entrant circuits. Under these conditions, the atria receive multiple impulses, which cause the atria to quiver rapidly (fibrillate), preventing efficient contraction. Cryoablation uses freezing temperatures to create lesions in the atria that prevent electrical conduction from ectopic triggers and re-entrant circuits, thereby stopping AF and restoring the heart to sinus rhythm.
