Figure 3 Fractionated Electrograms and Slow Conduction
The left panel shows the electrodes on the plaque that were fractionated (black) during pacing in a Group C (mitral regurgitation) patient. The right panel shows isochronal crowding at the site of the line of slow conduction seen during pacing from the septal inferior corner of the plaque. *Site of pacing. Note the site of fractionated electrograms matches the site of slow conduction during pacing.
