?Wolff-Parkinson-White syndrome
clinical significance from
Pediatric Cardiology theory and
practice of law


Wolff-Parkinson-White syndrome is a benign cardiac arrhythmias,
prevalent non-structural heart disease, few patients associated with
Ebstein, subaortic stenosis, mitral valve prolapse and Ventricular
septal defect, accidental myocarditis, after myocardial infarction.
Wolff-Parkinson-White syndrome itself does not produce hemodynamic
changes, do not cause symptoms, but can often cause serious
arrhythmias, or coexisting with other diseases have increased the
risk of sudden death. Wolff-Parkinson-White syndrome is approximately
60%-70% of paroxysmal supraventricular tachycardia, a pediatric
paroxysmal supraventricular tachycardia top reasons, it is atrial
impulses through normal AV to ventricular junction of organization,
and then passed back to the top by bypass, constantly reentrant
Atrium arising; or bypass to the ventricle, then from the normal AV
connections outside the reentrant to Atrium. More in children or
young people may be repeated during attacks, there is no evidence of
structural heart disease. Can also be combined with atrial
fibrillation (flutter), atrial fibrillation, ventricular rate
constant in 180 ~ 360/min, beware ventricular rate greater than 200
times/min, easy blackout or cardiogenic shock. Sudden death occurred
in ventricular fibrillation, atrial premature impulses too quickly
download, ventricular fibrillation, evoked easily ventricular
fibrillation, the treatment should be positive. Janet qilu hospital
