Abstract

A 29-year-old male presented to the cardiology department with a 2-day history of aggravating choking sensation in the chest and symptoms of heart failure. He had a history of congenital heart disease diagnosed at 2 years of age. Physical examination revealed orthopnea, cyanosis, apical impulse located on the right side of his chest, and hepatic dullness located in the left subcostal region. A 12-lead ECG is shown in Figure 1. The ECG was inconsistent with typical ECG characteristics of mirror-image dextrocardia because R wave progression occurred in leads V1 through V6, although the R wave amplitude decreased progressively. How should we analyze ECG combined with clinical findings to confirm our diagnosis? Please turn the page to read the diagnosis. Yuhong Li, PhD Renguang Liu, PhD Xianglin Zhang, MD Dextrocardia
