In 1930 Louis Wolff, Sir John Parkinson and Paul Dudley White described 11 patients who suffered from bouts of tachcyardias. Their ECGs showed two abnormalities: a short PQ time and a delta-wave. | In 1930 Louis Wolff, Sir John Parkinson and Paul Dudley White described 11 patients who suffered from bouts of tachcyardias.

Ever since one speaks of the '''Wolff-Parkinson-White syndrome''' in patients with complaints of syncope and / or tachycardia and a pre-exitation pattern on the ECG (WPW syndrome = WPW pattern + symptoms). Not all patients with a WPW ''pattern'' on the ECG are symptomatic. The prevalence of the WPW or pre-exitation pattern is relatively common in the general population (about 0.15-0.25%). | Ever since one speaks of the '''Wolff-Parkinson-White syndrome''' in patients with complaints of syncope and / or tachycardia and a pre-exitation pattern on the ECG (WPW syndrome = WPW pattern + symptoms).
