Ms. C, a very active professional woman who enjoyed skiing, scuba diving and sky-diving, was diagnosed with a cardiac arrhythmia and mitral valve prolapse in 1989.By 1993, she was experiencing 700 extra heartbeats per hour and was told that she was at risk for sudden death. She was prescribed beta-blockers, Valium and aspirin, the side effects of which were stomach-aches, headaches and hair loss. In July 1994, Ms. C suffered a near-fatal episode of ventricular tachycardia and underwent radio frequency catheter ablations. Ms. C’s ventricular tachycardia events continued to recur throughout the following nine months, during which time she had surgery four times. In April 1995, she was told that another catheter ablation might perforate her heart, causing death. Feeling like an invalid, depressed, and afraid to live, Ms. C was forced to take an extended medical leave from her high-level job at a global technology company. Ms.C describes herself during the period that preceded her illness as follows: “I was the type of person who was trying to be the perfect mother, the perfect wife, the perfect employee. I used to sleep four hours a night because there was so much to do. I thrived on it. I was so used to that adrenaline rush that I didn’t know what it was like not to have it”.
