Pre-excitation syndrome

Under pre-excitation is understood in the Rhythmology premature excitation of the heart chamber via a antegrade conducting, congenital path that is parallel to the atrioventricular node. About this track can cardiac arrhythmias, sg AV Reentrytachykardien ( AVRT ), are caused.

The ECG often the typical characters of the delta wave, a hump- shaped slow spread, shoulder is called, in the beginning of the R wave to thereby shortened PQ interval.

The first form was discovered the open Wolff- Parkinson -White syndrome (WPW syndrome). Under this term, the even Präexzitationssyndrome mentioned, combined diseases. There, these include

  • Open WPW syndrome,
  • Concealed WPW syndrome,
  • Permanent junctional reentrant tachycardia ( PJRT, Syn: Permanent junctional reciprocating tachycardia, permanent junctional Umkehrtachykardie ) and
  • Lown -Ganong -Levine syndrome ( LGL syndrome).
