Kristine Breese

Kristine Breese was a 33-year-old mother of two children, juggling family responsibilities and a full-time job in public relations. She had run several marathons and was training for a triathalon.

For 10 years, she had fainting spells that she thought were due to dehydration and stress (she fainted on her wedding day.) But when she fainted in front of a family member, she went to the emergency room.

Doctors ruled out several neurological problems, and during one of the final tests, a tilt-table test, Kristine went into cardiac arrest.

Since then, she has received a pacemaker and has gotten rid of some of her stress -- working at home and eliminating triathalons. She's written a book, "Cereal for Dinner: Shortcuts, Strategies & Sanity for Moms Battling Illness." St. Martin's Press released it in spring 2004.
