WPW is usually diagnosed with a standard electrocardiogram (ECG), but specialized testing is required in some patients. The electrocardiogram — The WPW pattern can be detected by an ECG, even while the patient is in a normal rhythm. Conduction through the accessory pathway produces a characteristic ECG pattern.
