Background: Wolff-Parkinson-White (WPW) syndrome is a proarrhythmic condition that may require restriction from strenuous activities and is characterized by ECG signs, including delta waves. We observed cases of intermittent WPW patterns presenting as QRS alternans ('WPW alternans') in a large pre-participation ECG screening cohort of young men reporting for military conscription.
Objectives: We aimed to determine the WPW alternans pattern, case characteristics, and the prevalence of other relevant differential diagnoses presenting as QRS alternans in a pre-participation setting.

ECG of patients with Wolf Parkinson White (WPW) syndrome may simulate other entities such as myocardial infarction, ventricular premature complexes, ventricular bigeminy, accelerated idioventricular rhythm, intermittent bundle branch block or electrical alternans. On the other hand, the opposite can also occur where these other conditions may simulate WPW. We present the case of a young patient referred for WPW ablation showing an incessant accelerated idioventricular rhythm mimicking preexcitation.

Article Synopsis
- Emergency physicians need to be able to quickly identify life-threatening conditions in patients presenting with abnormal heart rhythms, known as cardiac dysrhythmias.
- A case study describes a 31-year-old man who exhibited atypical dysrhythmia after reversing an opiate overdose, leading to the rare diagnosis of Wolff-Parkinson-White (WPW) alternans.
- The report emphasizes the importance of a systematic approach in evaluating electrocardiograms to recognize serious dysrhythmias and outlines the differential diagnosis for WPW patterns.
