I am 56 years old, and had a cardiac pacemaker
installed 17 years ago. I also have mild mitral valve prolapse, noticed when I was three; and aortic valve insufficiency, increasing slowly and first noticed after the pacemaker. I am 5 foot 9 inches, formerly 5' 11"; weight under 150 pounds, and exercise often, having bicycled over 150,000 miles the past 30 years. I am employed as an attorney.
