Figure 7: Relative changes of during rotation for distal electrode (orthogonal orientation and parallel orientation), ME2 (orthogonal orientation and parallel orientation), ME1, and ME3 in parallel orientation. The catheter is rotated above healthy myocardium. All were referenced to minimum of each electrode for complete rotation. At an angle around 30°, ME2 is in direct contact with the myocardium. Relative changes of for distal electrode are completely overlapping in both catheter positions.
