What causes sinus node dysfunction (SND)?

Reversible causes of sinus node dysfunction

• Age-related degenerative disease (development of fibrosis) of sinoatrial node.
• Myocardial ischemia/infarction.
• Perimyocarditis.
• Drug side effects (diltiazem, verapamil, beta-blockers, digitalis, amiodarone, klonidine, procainamide).
• Hypoxia (hypoxemia)
• Hyperkalemia.
• Hyperthermia
• Increased intracranial pressure

What is sinoatrial 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 is the prognosis for Sick sinus syndrome?

What causes sick sinus syndrome?

• Development of scar tissue. The most common cause of sick sinus syndrome is replacement of the normal pacemaker cells with scar tissue.
• Heart disease or heart attack. ...
• Disorders in heart function or heart trauma. ...
• Medications
• Toxins and abnormal electrolyte levels. ...
• Genetic mutations. ...

What is sinus 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 SSS?

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.

Is sinus node dysfunction considered heart disease?

Overview. Sick sinus syndrome is a type of heart rhythm disorder. It affects the heart's natural pacemaker (sinus node), which controls the heartbeat. Sick sinus syndrome causes slow heartbeats, pauses (long periods between heartbeats) or irregular heartbeats (arrhythmias).

What is severe sinus node dysfunction?

Description. 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.

Is atrial fibrillation sinus node dysfunction?

AF results in sinus node remodeling on a cellular and molecular basis that may promote SSS. However, not all patients with atrial fibrillation have SSS. Though “AF begets AF”, AF may also beget SSS; and SSS may also beget AF. Multiple studies have demonstrated that sinus node dysfunction may precede the onset of AF.

What is the ICD 10 code for SSS?

ICD-10 code I49. 5 for Sick sinus syndrome is a medical classification as listed by WHO under the range - Diseases of the circulatory system .

Why is it called sinus node?

The sinoatrial node (also known as the sinuatrial node, SA node or sinus node) is a group of cells known as pacemaker cells, located in the wall of the right atrium of the heart....Sinoatrial nodeSystemElectrical conduction system of the heartArterySinoatrial nodal arteryIdentifiersLatinnodus sinuatrialis8 more rows

What causes the 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 the sinus node the SA node?

The 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 is sinus node modification?

Sinus node modification is feasible in humans and should be considered as an alternative therapy for patients with disabling inappropriate sinus tachycardia refractory to medical management. The risk of need for permanent pacing increases with complete sinus node ablation.

What is the difference between atrial fibrillation and sick sinus syndrome?

What is the difference between sick sinus syndrome and atrial fibrillation (afib)? With sick sinus syndrome, your SA node isn't working correctly. With atrial fibrillation, rogue electrical signals in your upper chambers override your SA node's normal signals. This gives your upper chambers an abnormal beat.

What happens if the SA node is unable to function?

If the sinus node is not functioning normally — due to damage from surgery, drugs, congenital heart defects or other causes — the heartbeat may become very slow with a decrease in blood pressure. Sinus node dysfunction may lead to an abnormally slow heart rhythm called bradycardia.

What does SSS mean to the heart?

Sick sinus syndrome (SSS) is a disease in which the heart's natural pacemaker located in the upper right heart chamber (right atrium) becomes damaged and is no longer able to generate normal heartbeats at the normal rate.

Is sinus node dysfunction a disability?

Qualifying with Sinus Bradycardia Symptoms Bradycardia does not have its own listing in the Social Security Administration's (SSA's) Blue Book, which is a list of disabilities that qualify for SSD.

How is sinus node dysfunction diagnosed?

ECG Findings[2][13]: The key to diagnosing sinus node dysfunction is to establish a correlation between the patient symptoms and the ECG findings at the time of symptoms. It is also beneficial to review previous ECG tracing to check for any changes in the rhythm upon the start of the symptoms.

How do you treat SSS?

Treatment of sick sinus syndrome may include:Regular checkups.Medications.Catheter procedures.Surgery to implant a device to maintain a regular heartbeat (pacemaker)
