  Figure 1. Electrocardiogram Electrocardiogram performed revealing left bundle branch block and concurrent first-degree atrioventricular block.

• 

  Figure 2. Micra Atrioventricular Placement Contrasted right ventriculogram revealing adequate placement of Micra atrioventricular leadless pacemaker.

• 

  Figure 3. Electrocardiogram Comparisons Electrocardiogram obtained after placement of Micra right ventricular pacemaker alone (A, top), compared to electrocardiogram obtained after implantation of WiSE-CRT left ventricular electrode (B, bottom) unveiling reduced QRS duration.

• 

  Figure 4. WiSE-CRT Deployment This illustrates the WiSE-CRT left ventricular electrode (red arrow) with respective battery and transmitter (yellow arrows) with Micra atrioventricular pacemaker (blue arrow) in left anterior oblique projection.
