Chronic persistent AF has no widely accepted clinical definition or meaning.

Chronic AF, unspecified (I48.20) may refer to any persistent, longstanding persistent or permanent AF.Permanent AF (I48.21) is persistent or longstanding persistent AF where cardioversion cannot or will not be performed, or is not indicated.Persistent AF (I48.11) describes AF that does not terminate within seven days, or that requires repeat pharmacological or electrical cardioversion.This information is from the ICD-10-CM Official Guidelines for Coding and Reporting and the sources listed below*.Īccording to ICD-10-CM guidelines,these four unique codes describe the types of AF: Below are resources for documenting and coding atrial fibrillation (AF). The risk of sudden cardiac death is high, and a history of survived cardiac arrest at the initial presentation is a strong predictor of recurrent ventricular arrhythmias over the course of time.High quality documentation and complete,accurate coding can help capture our members' health status and promote continuity of care. Patients on quinidine should be carefully monitored for QT prolongation and possible pro-arrhythmic events. Quinidine prophylaxis may be considered in patients where ICD is contraindicated/refused or in asymptomatic SQTS patients with a family history of SDC. However, ICD is complicated by a high probability of inappropriate ICD shocks, particularly in pediatric patients, and requires appropriate programming to prevent T-wave oversensing. Management and treatmentĬurrently, an automatic implantable cardioverter-defibrillator (ICD) is recommended for patients who have experienced a sustained VT/VF episode or have survived an aborted cardiac arrest. First-degree relatives of an affected individual have a 50% risk of being affected. Genetic counseling should be offered to affected families. Of note, a few rare patients with Brugada syndrome have been reported to have a short QTc. Differential diagnosisĭifferential diagnosis includes other repolarizing disorders such as Brugada syndrome and early repolarization syndrome. When a patient is diagnosed, clinical assessment is recommended in all family members, including an ECG in newborns. Diagnostic methodsĪccording to the European Society of Cardiology Guidelines, SQTS is diagnosed by the presence of a corrected QT (QTc) interval less than or equal to 340 ms on resting 12-lead ECG or should be considered in the presence of a QTc less than or equal 360 ms and one or more of the following: a confirmed pathogenic mutation, a family history of SQTS, a family history of sudden death at young age (less than 40 years of age), or history of ventricular tachyarrhythmia/ventricular fibrillation (VT/VF) in the absence of heart disease. 40% of patients do not have a genetic cause identified. Mutations in the genes KCNQ1 (11p15.5), KCNH2 (7q36.1), and KCNJ2 (17q24.3), encoding cardiac ionic potassium channels, and the gene encoding the calcium channel, CACNA2D1 (7q21.11), have been identified in affected patients. The risk of sudden cardiac death (SDC) is highest in the first year of life and between 20 to 40 years. There is a high risk of recurrent arrhythmic events in symptomatic patients. Other symptoms include syncope and arrhythmias including atrial fibrillation, ventricular fibrillation (VF), supraventricular tachycardia (SVT), and polymorphic ventricular tachycardia. Whilst the disease may remain asymptomatic, the most common clinical presentation is a cardiac arrest (CA), with approximately 40% of patients suffering an episode of CA between birth and 40 years of age. The disease has been predominantly reported in males. This extremely rare syndrome affects mainly young adults or infants and has been reported in nearly 80 families.
