Figure 1From: Improved cardiac gating at 3T with the “3D-QRS” method utilizing MRI-compatible 12-lead ECGs3-D representations of the (a) SR-QRS complex, (b) VMHD and (c) the PVC-QRS complex, all of which have unique 3-D geometrical kernels. (d) Electrical signal propogate via different paths from the various heart sources to the surface leads V1-V6, which is reflected in their ECG channel's axes.Back to article page
