Differential Diagnosis from experts 2025:

Case Study: 18-Year-Old Male Presents After Syncopal Episode Chief Complaint : "I passed out while standing in line." History of Present Illness (HPI) : An 18-year-old male presents to the emergency department after a brief loss of consciousness while waiting in line at a concert. He reports feeling lightheaded and nauseous before "blacking out." He regained consciousness within a minute, without confusion, seizure-like activity, or incontinence. He had not eaten or drunk anything all day, and it was a hot, crowded environment. Past Medical History : Unremarkable Medications : None Allergies : None Family History : Negative for sudden cardiac death Social History : High school student, no drugs/alcohol/smoking Vital Signs :

• BP: 100/60 mmHg
• HR: 56 bpm
• RR: 14
• Temp: 36.8°C
• SpO₂: 98% on room air Physical Exam :
• General: Alert, oriented, well-appearing
• Cardiovascular: Normal S1/S2, no murmurs
• Neuro: Cranial nerves II-XII intact, no focal deficits
• Orthostatic vitals: Positive (↓ BP, ↑ HR upon standing) Labs/ECG :
• CBC/CMP: Normal
• ECG: Normal sinus rhythm, no QT prolongation
• Glucose: Normal
• Urine drug screen: Negative Assessment : Likely vasovagal syncope due to prolonged standing, dehydration, and heat exposure. Other differentials include orthostatic hypotension, cardiac arrhythmia, and seizure (less likely given history).

Plan :

• Rehydration
• Education on triggers and warning signs
• Consider tilt table test if episodes recur
• Outpatient cardiology referral if red flags develop Let me know if you'd like to build this out more, or focus on a different cause like cardiac syncope, hypoglycemia, or seizure!
