Wolff-Parkinson-White Syndrome (WPW) ECG of young lady who presented to the ER with episodes of chest pain, dizziness, and feeling a "black cloud coming over my vision." The PR interval is short and there are clear delta waves in multiple leads. These are both the result of pre-excitation down an accessory pathway! Look for WPW in all patients with syncope/palpitations. One day you will make a difference in someone’s life! - Sam Ghali, M.D. https://twitter.com/EM_RESUS/status #WolffParkinsonWhite #WPW #Syndrome #ECG #EKG #Electrocardiogram #Clinical
