Question: This ECG was made shortly after this patient had been resuscitated. The patient was normothermic. What arrhythmia likely initiated the syncope? What technical abnormality is seen?

A. This ECG shows a severely prolonged QTc interval, which makes the patient prone to Torsade de Pointes and potential ventricular fibrillation

B. Lead I has a negative P wave and Negative QRS complex. The arm leads were interchanged while recording this ECG.

C. The S in v1 + the R in v5 (equaling 35mm or greater) are indicative of left ventricular hypertrophy

Correct Answer:

A: This ECG shows a severely prolonged QTc interval, which makes the patient prone to Torsade de Pointes and potential ventricular fibrillation
