Junctional ectopic tachycardia (JET) is a rare syndrome of the heart that manifests in patients recovering from heart surgery.[1] It is characterized by cardiac arrhythmia, or irregular beating of the heart, caused by abnormal conduction from or through the atrioventricular node (AV node).[2][3] In newborns and infants up to 6 weeks old, the disease may also be referred to as His bundle tachycardia or congenital JET.
