32-year-old female with dextrocardia and congenital heart blocking. Prepacemaker electrocardiogram. A. The leads are placed to the right. B. The precordial leads are placed to the left. Notice the R wave progression in the precordial leads versus the poor progression seen in B. Evident are the right axis deviation and the complete heart block with prolonged PR interval. Also note the inverted P waves in leads I and AV, L indicating dextrocardia. Notice in B the low voltage seen in V4, V5, V6.
