#29 in the running - change the gray to blue? black? "modernize" or striations in the middle of the heart? striations on an angle on the inside of the heart to project speed and action?
#48 and #49 I like both a lot, but the Red lettering in the Group emphasizes the wrong word. Perhaps instead of gray, use black or dark Blue? for Cardiology - much better than #29
58 - a version where the name stands out better? More Navy color? A little too bottom heavy? - most common use will be at the top of stationary and business cards, and dont what a lot of "dead space" at the top - I don't know if it will work as well though. Your thoughts, comments appreciated.
308, 309 good -- but move logo to left, Group seems bigger than Cardiology, and change the up and down line to a true ECG signal - P wave, a QRS, and a Twave
