Fresh, professional, funky? logo for medical training company

The Heart Center

The Heart Center will primarily be an American Heart Association CPR and Advanced Life Support training company. Our tag line is: Critical Response Training and Consulting.
We will deliver high quality training programs at the location of the clients choosing.
The client base is diverse and ranges from mothers desiring peace of mind to Doctors demanding high level training and consulting.
The logo needs to be fresh and welcoming yet professional. Most of our clients and business will come from CPR training but that should not be the focus of the logo.
Let your imagination run wild. No color schemes have been set but please do not let the logo appear feminine due to the likely desire to include a heart in the design.
The high level training we provide is the "code blue" type knowledge and skills Doctors, nurses, paramedics need when trying to resucitate a patient.
Please Help! this is a start-up one person operation that will attract a large portion of its clientel through our website. Your design could lead to web design and other design work in the coming weeks.

No Feminine heart designs. Hearts are fine but not girly ones.
EKG tracings are fine but almost as cliche as hearts.
Funky/professional...is that possible?
