Diagnostic Considerations

Important considerations

Identify junctional ectopic tachycardia (JET) in a neonate to avoid the potential for development of tachycardia-induced cardiomyopathy and sudden death.

Other conditions to consider in the diagnosis of JET include accelerated junctional rhythm and permanent junctional reciprocating tachycardia.

Promptly identify postoperative JET to avoid the potential development of rapid hemodynamic compromise and death.

Special concerns

In patients undergoing surgery for tetralogy of Fallot, avoiding resection and excessive traction of the right ventricular outflow tract may decrease the chances of developing postoperative JET.
