PY - 2022 T2 - Current Medical Diagnosis & Treatment 2022 AB - ESSENTIALS OF DIAGNOSISTwo classic features of Wolff-Parkinson-White (WPW) pattern on ECG are short PR interval and wide, slurred QRS complex due to manifest preexcitation (delta wave).Most patients with WPW pattern do not have clinical history of arrhythmia but have a higher risk of sudden cardiac death due to rapidly conducted atrial fibrillation through the accessory pathway. Risk factors include age younger than 20, history of tachycardia, and rapid conduction properties at electrophysiologic testing.
