What is sinoatrial node dysfunction?

Sinus node dysfunction, previously known as sick sinus syndrome, describes disorders related to abnormal conduction and propagation of electrical impulses at the sinoatrial node. An abnormal atrial rate may result in the inability to meet physiologic demands, especially during periods of stress or physical activity.

Is sinus node dysfunction the same as sinoatrial node dysfunction?

Sinus node dysfunction (SND) is characterized by dysfunction of the sinoatrial (SA) node that is often associated with senescence of the node and surrounding atrial myocardium.

Does SA node dysfunction cause atrial fibrillation?

Abstract. Background: Symptomatic sinus node dysfunction (SND) consists of a variety of manifestations, including tachycardia-bradycardia syndrome. Atrial fibrillation (AF) is commonly associated with SND, which complicates the management of both conditions.

What causes sinus node dysfunction?

Sinus node dysfunction results from the abnormal automaticity, conduction, or both of the sinoatrial node and surrounding tissues. Both could result from abnormal mechanisms, including fibrosis, atherosclerosis, and inflammatory/infiltrative processes.

Is sinus node dysfunction the same as sick sinus syndrome?

Sick sinus syndrome may also be called sinus node dysfunction or sinus node disease.

What is the other name of SA node?

the sinus nodeThe SA node, also known as the sinus node, represents a crescent-like shaped cluster of myocytes divided by connective tissue, spreading over a few square millimeters. It is located at the junction of the crista terminalis in the upper wall of the right atrium and the opening of the superior vena cava.

What happens to the SA node during atrial fibrillation?

During AFib, the heart receives electrical signals that come from outside the SA node causing the atria to contract in a disorganized fashion. This causes the atria to quiver (fibrillate). The disorganized signals are then transmitted to the ventricles. It causes them to contract irregularly and sometimes quickly.

Is the SA node a nerve?

The parasympathetic nerves supplying the SA node (in particular the Vagus nerves) originate in the brain. These nerves release a neurotransmitter called acetylcholine (ACh).

What happens to SA node in AF?

When the SA node fires an impulse, electrical activity spreads through the right and left atria, causing them to contract and force blood into the ventricles. The impulse travels to the atrioventricular (AV) node, located in the septum (near the middle of the heart).

Where is the SA node is located?

right atriumIntroduction. The sinoatrial node (SAN), located in the right atrium, serves as the primary site for initiation of the normal heartbeat (sinus rhythm) (Figure 1).

What is the name of the heart node that is affected by sinus node dysfunction?

Sick sinus syndrome Sick sinus syndrome (also known as sinus node dysfunction) is a group of related heart conditions that can affect how the heart beats. "Sick sinus" refers to the sino-atrial (SA) node, which is an area of specialized cells in the heart that functions as a natural pacemaker.

What is sinus syndrome?

a condition caused by dysfunctions related to the sinoatrial node including impulse generation cardiac sinus arrest and impulse conduction sinoatrial exit block. it is characterized by persistent bradycardia chronic atrial fibrillation and failure to resume sinus rhythm following cardioversion. this syndrome can be congenital or acquired particularly after surgical correction for heart defects.

In people with sick sinus syndrome, the SA node does not function normally. In some cases, it does not produce the right signals to trigger a regular heartbeat.

What is a sa node?

It may be associated with bradycardia-tachycardia syndrome. A derangement in the normal functioning of the sinoatrial node. Typically, sa node dysfunction is manifest as sinoatrial exit block or sinus arrest, but may present as an absolute or relative bradycardia in the presence of a stressor. It may be associated with bradycardia-tachycardia ...

What is the ICd 9 code for a syringe?

What is sinus node dysfunction?

Sinus node dysfunction refers to a number of conditions causing physiologically inappropriate atrial rates. Symptoms may be minimal or include weakness, effort intolerance, palpitations, and syncope. Diagnosis is by electrocardiography. Symptomatic patients require a pacemaker.

What happens to the SA node in an exit block?

In SA exit block, the SA node depolarizes, but conduction of impulses to atrial tissue is impaired.

What is sinus pause?

Sinus pause is temporary cessation of sinus node activity, seen on electrocardiography (ECG) as disappearance of P waves for seconds to minutes. The pause usually triggers escape activity in lower pacemakers (eg, atrial or junctional), preserving heart rate and function, but long pauses cause dizziness and syncope.

What causes SA node fibrosis?

Other causes include drugs, excessive vagal tone, and many ischemic, inflammatory, and infiltrative disorders.

Can sinus node dysfunction cause bradycardia?

Symptoms and Signs of Sinus Node Dysfunction. Many patients with sinus node dysfunction are asymptomatic, but depending on the heart rate, all the symptoms of bradycardias and tachycardias can occur .

What causes sinus node dysfunction?

Causes. Sinus node dysfunction can be caused by intrinsic and extrinsic factors that affect the normal functioning of the sinus node. Intrinsic causes can include degeneration, dysfunction, or remodeling of the sinus node while extrinsic causes can create or worsen underlying atrial arrhythmias.

What is the most common complication of sinus node dysfunction?

The most common complication of sinus node dysfunction is the development of tachycardia-bradycardia syndrome with abnormal atrial rhythms such as atrial tachycardia, atrial fibrillation, and flutter. These rhythms increases the risk of clot formation in the atrium, embolization, and stroke. Developing sinus arrest, sinus node exit block, sinus ...

What is the primary finding of a 12-lead electrocardiogram?

The primary 12-lead electrocardiogram (ECG) finding in sinus node dysfunction is inappropriate sinus bradycardia. Sinus node dysfunction can also present with sudden sinus arrest with or without junctional escape, sinoatrial block, prolonged asystolic period followed by tachycardias, or tachycardia-bradycardia syndrome presenting as various atrial arrhythmias such as atrial fibrillation, flutter, tachycardia, or paroxysmal supraventricular tachycardia.

How many people have sinus node dysfunction?

Overall incidence of sinus node dysfunction increases with age with 1 in 1000 in adults over 45 years old and 1 in 600 cardiac patients over 65 years old . Sinus node dysfunction is the primary indication for approximately 30%-50% of all pacemaker implantation in the United States. Sinus node dysfunction is a relatively uncommon syndrome in the young and middle-aged population.

What is the name of the disorder that causes abnormal heart rhythms?

Complications. Tachycardia-bradycardia syndrome. Sinus node dysfunction (SND), also known as sick sinus syndrome (SSS), is a group of abnormal heart rhythms ( arrhythmias) usually caused by a malfunction of the sinus node, the heart's primary pacemaker. Tachycardia-bradycardia syndrome is a variant of sick sinus syndrome in which ...

Can sinus node dysfunction cause shortness of breath?

Often sinus node dysfunction produces no symptoms, especially early in the disease course. Signs and symptoms usually appear in more advanced disease and more than 50% of patients will present with syncope or transient near-fainting spells as well as bradycardias that are accompanied by rapid heart rhythms, referred to as tachycardia-bradycardia syndrome Other presenting signs or symptoms can include confusion, fatigue, palpitations, chest pain, shortness of breath, headache, and nausea. Patients can also present with symptoms of congestive heart failure, stroke or transient ischemic attacks due to the abnormal rhythm.

Can a beta blocker cause sick sinus syndrome?

Common cardiac pharmacology such as beta-blockers, calcium channel blockers, digoxin, sympatholytic medication, and other antiarrhythmics can alter sinus node function to create an arrhythmia such as sick sinus syndrome . Electrolyte abnormalities such as hyperkalemia, hypokalemia, and hypocalcemia can also alter normal sinus node functioning.

What is sinus node dysfunction?

Sinus node dysfunction (SND) refers to a wide range of abnormalities involving sinus node and atrial impulse generation and propagation. SND occurs at any age and is commonly encountered in clinical practice.

What causes SND in the sinoatrial node?

Degenerative and/or fibrotic changes in the sinoatrial (SA) node region are the predominant cause of intrinsic changes that lead to SND. 5, 7, 8 These changes may result from ischemia, inflammation, surgical trauma, or as part of the aging process. 6 With age, the intrinsic HR (defined as the HR in the absence of autonomic nerve activity) declines, and SA conduction time (SACT) increases; 9 age-related changes in ion channels have been suggested as a possible cause. 3 However, these pathologic changes may also result from concomitant conditions such as hypertension, atherosclerotic cardiovascular disease, cardiomyopathy, infiltrative disease, myocarditis, and collagen vascular diseases. 2, 8, 10, 11 Since SND is typically diagnosed in individuals in their 70s or 80s, coexisting cardiovascular disorders are likely. 2

How to treat sinus node depression?

Treatment of SND is directed toward alleviating symptoms, and management should begin with a search for reversible causes of sinus node depression; this includes consideration of medications, autonomic dysfunction, and ischemia. Antiarrhythmic agents (including beta-adrenergic blockers and calcium channel blockers) and other medications can suppress sinus node function. 14 Whenever possible, an alternative medication that may be equally effective without slowing the HR should be selected. Although theophylline and beta-adrenergic agonists may still be used in isolated cases to treat symptomatic bradycardia, they do not prevent syncope 4 and are not commonly employed in the treatment of SND.

What is SND in medical terms?

1 SND refers to a wide range of abnormalities involving sinus node and atrial impulse generation/propagation. 2, 3 Although SND occurs at any age, the incidence increases exponentially with advanced age, 3 the mean age for diagnosis is 68 years, and both genders are equally affected. 4, 5 The incidence of this disorder is difficult to establish since it may be intermittent, and patients may be free from symptoms for many years. Furthermore, when the patient is symptomatic, the symptoms may be attributed to some other cause. Available estimates are that SND occurs in 1 of every 600 cardiac patients over age 65 and accounts for approximately half of the pacemaker implants in the United States. 5 Therefore, SND can be commonly encountered in clinical practice. As such, clinicians must be able to accurately diagnose this syndrome, which can present from asymptomatic bradycardia to atrial standstill.

How does parasympathetic stimulation affect sinus node function?

Parasympathetic stimulation slows the sinus discharge rate and increases the intranodal conduction time, resulting in sinus node exit block at times . 4 Individuals with conditions such as vasovagal syncope and carotid sinus hypersensitivity frequently have associated bradycardia. 4, 8 Heightened vagal tone from excessive physical training may result in syncope related to bradycardia or atrioventricular (AV) conduction abnormalities in otherwise healthy individuals. 7

What are the pathophysiologic mechanisms of SND?

The pathophysiologic mechanisms for SND include failure of impulse generation and failure of the impulse to spread throughout the atria. 3 In addition, there may be failure of secondary pacemaker activity (AV junction and Bundle of His) manifested as failed escape rhythms and increased atrial vulnerability to fibrillation and other tachydysrhythmias. 8 Atrial fibrillation results in sinus node remodeling on a cellular and molecular basis that may promote SND. 16

What are the symptoms of SND?

They are also related to a reduction in cerebral or peripheral perfusion and abrupt changes in HR. Symptoms are diverse and range from the following: non specific complaints of fatigue, palpitations, irritability, lassitude, lack of concentration, forgetfulness to the more dramatic symptoms of syncope, recurrent dizziness, and heart failure. 14, 17 In some cases, stroke may be the first indication of SND in patients with paroxysmal atrial fibrillation and thromboembolism. 4 Furthermore, unrecognized SND may manifest as a perioperative complication that can cause various dysrhythmias—even cardiac arrest. 18
