Case Report (n=1)
An ECG challenge presenting a 70-year-old man with wide QRS complex tachycardia for diagnostic evaluation.
Highlights diagnostic pitfalls in wide QRS tachycardia; leaves open validation of ECG algorithms in prospective cohorts.
ECG CHALLENGEA 70-year-old man was admitted to the emergency department for several hours of palpitations, dizziness, and dyspnea.The patient had a history of hypertension, diabetes mellitus, dyslipidemia, chronic obstructive pulmonary disease, and paroxysmal atrial fibrillation.His medications included eprosartan, amlodipine, atorvastatin, sitagliptin, indacaterol, and acenocoumarol.On arrival, his heart rate was 170 bpm and blood pressure was 110/50 mm Hg.The following 12-lead ECG was obtained (Figure 1).Based on the ECG, what is the most likely diagnosis?Please turn the page to read the diagnosis.
