Amiodarone successfully resolved ventricular tachycardia in a patient presenting with an irregular wide QRS tachycardia initially misdiagnosed as atrial flutter with an accessory pathway.
Case Report (n=1)
This case highlights the challenge of differentiating wide QRS tachycardias and emphasizes the importance of analyzing QRS morphology and atrioventricular relationship for accurate diagnosis.
We report a 69-year-old woman with persistent palpitation, a history of myocardial infarction. ECG showed irregular wide QRS tachycardia with positive precordial concordance and flutter waves, initially misdiagnosed as atrial flutter with accessory pathway. Direct current cardioversion restored sinus rhythm but failed to terminate tachycardia, revealing ventricular tachycardia (VT). Amiodarone resolved VT. This case highlights the challenge of differentiating wide QRS tachycardias, emphasizing QRS morphology and atrioventricular (AV) relationship analysis for accurate diagnosis.
Ren et al. (2026) conducted a case report in Ventricular tachycardia (n=1). Direct current cardioversion and Amiodarone was evaluated. Amiodarone successfully resolved ventricular tachycardia in a patient presenting with an irregular wide QRS tachycardia initially misdiagnosed as atrial flutter with an accessory pathway.
