Supraventricular tachycardia with an accessory connection mediated pathway

MedGen UID:
866781
Concept ID:
C4021132
Disease or Syndrome
Synonyms: Atrioventricular re-entry tachycardia; Supraventricular tachycardia with an accessory connexion mediated pathway
 
HPO: HP:0011688

Definition

Supraventricular tachycardia in which an accessory pathway connecting the atria and ventricles, apart from the AV node, participates as a necessary part of a reentrant mechanism. [from HPO]

Conditions with this feature

Brugada syndrome 1
MedGen UID:
1646402
Concept ID:
C4551804
Disease or Syndrome
Brugada syndrome is characterized by cardiac conduction abnormalities (ST segment abnormalities in leads V1-V3 on EKG and a high risk for ventricular arrhythmias) that can result in sudden death. Brugada syndrome presents primarily during adulthood, although age at diagnosis may range from infancy to late adulthood. The mean age of sudden death is approximately 40 years. Clinical presentations may also include sudden infant death syndrome (SIDS; death of a child during the first year of life without an identifiable cause) and sudden unexpected nocturnal death syndrome (SUNDS), a typical presentation in individuals from Southeast Asia. Other conduction defects can include first-degree AV block, intraventricular conduction delay, right bundle branch block, and sick sinus syndrome.
