SinghMD.comLogo Design Contest

Health doesn't come from healthcare

I am a cardiologist interested in health and wellness and am starting a blog on heart disease and healthy living. My current logo's tagline is too small (maybe I shouldn't include my tagline in the logo?) . I wanted to incorporate a heart into my logo name which is SinghMD.com, though am not locked into it. If you look at that site that is up and running http://www.singhmd.com you can see my current logo.

I like Blue and Green.

Open to all concepts. My current logo has an EKG rhythm on it. I am not opposed to having an EKG on it going forward but was hoping for a nicer look. A heart is also an option, perhaps as a background type image but not locked into this either. I have my current tagline in the logo presently though I know it is a bit lengthy thus if a nicer logo can be obtained without the tagline I am ok with that also.
I do not want it cartoonish. It needs to be professional and reflective of me, articulate, professional, cardiologist.
