Key result
Pseudoephedrine was identified as a trigger for sustained posterior fascicular left ventricular tachycardia in a single patient case.
Case Report (n=1)
This is the first reported case of pseudoephedrine triggering posterior fascicular left ventricular tachycardia.

May prompt avoiding pseudoephedrine in patients with fascicular VT history; single-case observation leaves association unconfirmed.
Immediate diagnosis and prompt treatment of wide QRS-complex tachycardia is vital. Differential diagnosis of wide QRS tachycardia is also challenging. The most common cause of wide QRS-complex tachycardia is ventricular tachycardia (VT). Idiopathic fascicular left ventricular tachycardia is a rare form of VT, and observed often in young and individuals without underlying heart disease. Clinical presentations are recurrent episodes of palpitations and dizziness without a trigger factor. The paper introduces a case of sustained posterior fascicular left ventricular tachycardia triggered by pseudoephedrine.
