Figure 4From: Cardiovascular magnetic resonance guided electrophysiology studiesA) Example of the bipolar intracardiac electrograms during scanning before filtering (bottom trace) and after filtering (top trace). B) Example of bipolar intracardiac electrograms at various locations in the heart outside the scanner (left column) and during scanning with different levels of filtering (right column). RA = Right atrium, His = His bundle, RV = right ventricular apex.Back to article page
