WEBFeb 2, 2022 · WPW Syndrome refers to the presence of a congenital accessory pathway (AP) and episodes of tachyarrhythmias. The term is often used interchangeablely with pre-excitation syndrome. First described in 1930 by Louis Wolff, John Parkinson and Paul Dudley White. Incidence is 0.1 – 3.0 per 1000.

WEBMay 15, 2024 · WPW is usually diagnosed with a standard ECG, but specialized testing is required in some people. The electrocardiogram — The WPW pattern can be detected by an ECG even while the person is in a normal rhythm. Conduction through the accessory pathway produces a characteristic ECG pattern.

WEBWolff-Parkinson-White (WPW) syndrome. An individual with evidence of pre-excitation on resting ECG who also has recurring tachyarrhythmias is said to have Wolff-Parkinson-White syndrome. This is actually a rather common condition and some studies suggest that the prevalence is 1–2 in 1000 in the population.
Ventricular pre-excitation (Wolff-Parkinson-White pattern)
WEBDec 18, 2012 · The pre-exitation pattern is caused by an extra connection between the atria and the ventricles (accessory bundle) that forms an electrical bypass to the AV node. The part of the ventricle where this accessory bundle connects are the first to depolarize. This is shown on the ECG as a delta wave.
