Using the HDG catheter, the EAM uses the high\u2010density (HD) wave mapping and best duplicate software to compare the maximum peak\u2010to\u2010peak bipolar voltages within a small zone independent of wavefront direction and catheter orientation.

Clinically indicated left and\/or right ventricular (LV, RV, respectively), and aortic maps were created.
