The right precordial leads revealed right bundle branch block, left precordial leads revealed LBBB and absence of deep and wide S waves in leads V5, V6 and I (precordial type MBBB) as shown in Figure 1. 
Posterior-anterior view of chest X-ray showing cardiomegaly with a CTR of 185/285 (65%), unfolded aorta, cephalization and bilateral hilar fullness with associated peribronchial cuffing.
