The later ICDs are more sophisticated and do a better of of identifying V-tach correctly and attempt to pace me out of V-tach before shocking. In the course of replacing tone
ICD, I got an infection and the
ICD and leads had to be removed and placed on the right side. Through all of this, I continued to exercise, but gave up competitive racing.
In the last couple years, the V-tach returned about 1 or 2 times per month.
