Sinus Node Dysfunction
Reversible causes of 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 causes sick sinus syndrome?
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.
Sinus node dysfunction is a disease that is characterized by the inability of the sinoatrial node of producing an adequate heart rate that meets the physiologic needs of an individual.
(Sick Sinus Syndrome) 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.
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 .

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.

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 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.

I49. 5 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2022 edition of ICD-10-CM I49. 5 became effective on October 1, 2021.
