The Value of Voltage Histogram Analysis Derived Right Atrial Scar Burden in the Prediction of Left Atrial Scar Burden

Figure 1

High-density electroanatomic bipolar voltage maps of two representative patients (posteroanterior (PA) view). Patient 1, an example with low amount of the low-voltage area (Quartile 1, Q1) in the left atrium (LA) and right atrium (RA). Patient 2, an example with Quartile 4 (Q4) diseased tissue of the left and the right atrium.
