Unusual Electrocardiogram in Dextrocardia.

The case here described was found in the course of a mass radiographic survey. Case History.-The patient was a well-grown man aged 35 years. He was free from symptoms. He had no significant past medical history. He had always lived a normal life and had been moderately athletic in his school days. On clinical examination it was found that cardiac pulsation was palpable in the right fourth intercostal space just internal to the mid-clavicular line. Normal heart sounds were heard in this area and between it and the sternum. At the left border of the sternum sounds were faint and further to the left were inaudible. No bruits were heard. There was no dyspncea, cyanosis, clubbing of the fingers, or other indication of cardiac disorder. Blood pressure was 120/70. Radiography showed a heart in the position of complete dextrocardia, but otherwise of normal contour. The lung fields were clear. The left dome of the diaphragm was raised. The liver and stomach were not transposed. Electrocardiographic Findings.-A cardiogram consisting of the three standard limb leads and three chest leads is shown in Fig. 1.
