2. Figure 1
The electrocardiogram (ECG) initially read as left bundle branch block. The QRS complexes are labeled 1-13 between the V5 rhythm strip (bottom) and the standard lead II rhythm strip (second from the bottom). Arrowheads indicate P waves in complexes 1-10, and an arrow indicates that complex 9 is a fusion complex.
