So, when the atrial fibrillation suddenly stops, the sinus node may require several seconds to "wake up" and begin generating electrical impulses again. Sick sinus syndrome is a condition in which the normal pacemaker of the heart is unable to keep the heart beating at a normal rate or rhythm to deliver blood to the body. In these cases, the chief problem is an inability to increase the heart rate appropriately during activity, a condition called "chronotropic incompetence.

When Is a Pacemaker Needed for Heart Block? Sick sinus syndrome is a disorder of older people and is most commonly seen in people over 70 years of age., he most common cause of sick sinus syndrome is age-related change, like fibrosis, affecting the sinus node (the tiny structure in the right atrium that generates the heart’s electrical impulse). “Fibrosis” means that normal tissue is replaced by a form of scar tissue. Choudhury M, Boyett MR, Morris GM. In a normal heart rhythm, a tiny cluster of cells at the sinus node sends out an electrical signal. In sick sinus syndrome, the electrical signals are abnormally paced. The disorder is usually seen in people over the age of 50 and is caused by damaged pathways in the heart. Hayes DL.

Because chronotropic incompetence is a fairly common condition in the elderly and is readily treatable (with a rate-responsive pacemaker), it is important for older people who are experiencing fatigue with mild or moderate exertion to self-advocate for proper evaluation. Sick sinus syndrome is a relatively rare disease that occurs more often in older people that may eventually require a pacemaker to restore the heart’s normal rhythm [1]. Accessed Jan. 23, 2020. Implanting a pacemaker will prevent syncope, and will allow the doctor to treat atrial fibrillation much more safely. Journal of the American College of Cardiology. The sinus node is the normal pace-maker of the heart and is responsible for the regular, rhythmic heartbeat. The sick sinus syndrome includes symptoms and signs related to sinus node dysfunction. Sick sinus syndrome is characterised by persistently slow heart rate, decreased heart rate response to exercise, sudden pauses in the normal activity of the sinusnode (sinus arrest or sinoatrial block) and occasional episodes of nodal or atrial escape rhythm. During this interval, there may be no heartbeat at all for 10 or more seconds — leading to extreme lightheadedness, or syncope. Sinus node dysfunction (SND), also historically referred to as sick sinus syndrome, is characterized by dysfunction of the sinoatrial (SA) node that is often secondary to senescence of the SA node and surrounding atrial myocardium. If it does, sinus bradycardia may be accompanied by episodes of heart block. Pacemakers. Cause .

Symptoms of sick sinus syndrome — such as dizziness, shortness of breath and fainting — are symptoms of numerous conditions. Sick sinus syndrome. The most common clinical manifestations are syncope, presyncope, dizziness, and fatigue. Sinus Arrest, Sinus Block, and Sick Sinus Syndrome Cardiac Review – Slides . Because the fibrosis that causes sinus node disease sometimes affects the AV node, people with brachy-tachy syndrome may also have a partial heart block, and therefore, a relatively slow heart rate when they are in atrial fibrillation. National Library of Medicine Genetics Home Reference. © 1998-2020 Mayo Foundation for Medical Education and Research (MFMER). The sinus node acts as a pacemaker inside of … The most prominent symptoms are usually those due to a slow heart rate, and include:, In some people with sick sinus syndrome, these symptoms will only occur when they attempt to exert themselves, and they will feel perfectly well while at rest. Accessed Jan. 23, 2020. When a person who complains of typical symptoms is found to have significant sinus bradycardia on their electrocardiogram (ECG), sick sinus syndrome may be diagnosed. So, whenever a person with atrial fibrillation is discovered to have a relatively slow heart rate (in the absence of medication aimed at slowing the heart rate), it gives the doctor a strong clue that sick sinus syndrome is likely also present.
