Right: An illustration of the heart showing the disposition of the recording electrodes (numbered red dots) and the stimulation electrode (green diamond) along the x-axis. Left: The top 2 images are UCSDI bipolar M-mode plots corresponding to the lateral line z = 100 mm. The image at the top was measured on electrodes 1 and 2 while the image below it was measured with electrodes 2 and 3. In the plot second to bottom are low frequency ECG plots measured concurrently on the same electrodes. The solid blue line was measured with electrodes 1 and 2 while the green dashed line was measured with electrodes 2 and 3. At the bottom are the tracking results corresponding to x = 0.54 mm in the top M-mode image. The vertical dashed line in all of the images marks t = 0. The slanted dashed white line in the second row was used to estimate the velocity of the activation wave.
