Figures

Figure 1
Figure 1
Prior to pacemaker implantation, the patient’s baseline electrocardiogram (ECG) disclosed sinus rhythm with premature atrial contractions, narrow QRS complexes, and normal T-wave orientation.
Figure 2
Figure 2
The ECG obtained 1 week after pacemaker implantation showed new T-wave inversions in leads II, III, aVF, and V3–V6.
Figure 3
Figure 3
An ECG obtained during right ventricular pacing via the patient’s pacemaker demonstrated that the paced QRS complexes were negative in leads that had new T-wave inversions (II, III, aVF, and V3–V6).
