Brief History
• 38 years old male without any systemic disease or regular medication
• Complained of palpitation frequently during past few months
• Tachycardia with stable vital sign during palpitation at emergency room

Differential Diagnosis
• Multifocal atrial tachycardia with aberrantconduction
• Ventricular tachycardia with AV dissociationwith frequent atrial premature complex
• Ventricular tachycardia with sinus P wave andretrograde VA conduction P wave
