Remember that T wave inversions and ST segment depression is normal in leads V1 - V3 in the presence of a RBBB, this technically myocardial ischemia can not be easily determined in these leads.

The correct diagnosis is sinus rhythm, RBBB, and V1-V3 lead switch (Figure 2). Figure 2. Courtesy of Philip J. Podrid, MD. The rhythm is regular at a rate of 64 beats/min, and the P waves (+) are ...

The first two complexes in leads V-V3 (+) are wide and show a right bundle branch block (RBBB) morphology with an RSR' morphology in lead V1 (←). These two complexes are preceded by a long (↔ ...
