Exercise Stress Test For Detecting High-Risk Accessory Pathways In Patients With Wolff-Parkinson-White Syndrome

In the description of Wolff, Parkinson, and White in 1930 of accessory pathway exhibiting antegrade conduction much work had been done to describe the anatomy, electrophysiology, and natural history of the syndrome. During sinus rhythm, a typical pattern in the resting electrocardiogram (ECG) is present: a short PR interval (< 120ms), a slurred upstroke or downstroke of the QRS complex (known as Delta wave), and a wide QRS complex (>120ms). In most cases, accessory pathways giving rise to the WPW [...]
