An Irregular Wide Complex Tachycardia.
A 66-year-old woman with a history of hypertension and persistent atrial fibrillation was referred to the Arrhythmia Clinic. Before her visit, a routine 12-lead ECG was ordered (Figure 1). The patient was asymptomatic except for minor palpitations. Her medicine regimen included apixaban, flecainide 150 mg twice daily, lisinopril, loratadine, metoprolol, and simvastatin. What is the cardiac rhyt...
متن کاملWide QRS Complex Tachycardia
