case_images: An ECG was obtained and it showed a QTc of 468 ms (16.4% increase) with biphasic T wave in Lead III (Figure 2).
case_images: Electrocardiogram revealed a sinus rhythm with slight ST elevation in leads V4 and V5. The QTc was 425 ms, a reduction of 9.2% as compared to the previous reading.
