Wolff-Parkinson-White syndrome

[Louis Wolff, U.S. cardiologist, 1898–1972; Sir John Parkinson, Brit. physician, 1885–1976; Paul Dudley White, U.S. cardiologist, 1886–1973]


A disease manifested by occasional episodes of potentially life-threatening tachycardia, in which there is an abnormal electrical pathway in the heart connecting the atria to the ventricles.


In some families, the disease is transmitted as an autosomal dominant trait.


In electrocardiography, the P-R interval is less than 0.12 sec and the QRS complex is widened as a result of an initial electrical deflection, called the delta wave.


Ablation of the abnormal accessory pathway cures about 92% of patients.

We report this case because it presented as supraventricular tachycardia in a previously apparently normal individual and investigation revealed both WPW syndrome and Rheumatic Mitral stenosis --a rare combination.
If untreated, tragically one in 1000 WPW patients suffer sudden collapse and death.
El especialista aclaro que este padecimiento no conduce a la muerte; sin embargo, existe el riesgo del fallecimiento si el joven con WPW se desmaye y se golpee con fuerza la cabeza o cae desde una altura considerable.
The Inverse of the Entire Filled PW (IEFPW) is given by an logical 'XOR' between the WPW and WIA IEFPW = XOR(WPW, WIA) Figure 10 shows the result.
Various forms of WPW syndrome are described (exact WPW syndrome, latent ventricular preexcitation, permanent junctional reciprocating tachycardia) in a presence of aberrant atrioventricular pathways in heart.
Though written at the time of Lyrical Ballads, in 1798, the work was not published until 1819, by which point Wordsworth's own self-image and reception had much changed (see WPW 188 ft.

Se aplica la denominacion de sindrome de WPW a los pacientes con pre-excitacion en el electrocardiograma y taquicardia paroxistica.
As shown in Figure 4, PLW and WPW had similar changes in the width, as did PLM and WPM.
Las taquicardias supraventriculares responsables de producir taquiarritmias de complejos anchos son llamadas tambien taquicardias supraventriculares con conduccion ventricular aberrante, lo cual hace referencia a una conduccion en forma asincronica, no simultanea de un impulso supraventricular hacia los ventriculos lo que conlleva a la produccion de un complejo QRS ancho; como sucede con el bloqueo de rama del haz de His de tipo funcional (temporal), el bloqueo de rama del haz de His preexistente (permanente) o los complejos QRS preexcitados por una conexion auriculoventricular (AV) accesoria como es el caso del sindrome de WPW (1).
