My ICD is literally a lifesaver. After a septal myectomy I had dizziness and later 2 syncopes. I was SO, SO HAPPY when it was installed and these two aftereffects immediately ceased. I slept in a recliner for a short time, was not to not reach above shoulder level for a short while and the incision healed quickly. Can't hold babies on that side and have to remember to avoid turning my upper body tightly to the right. I tell them at airports and am screened differently, I am often told to just walk around other screening situations. It's always scary to deal with medical interventions, evaluating the pros and cons along with asking your cardiologist any questions will help you to make the best decision for yourself.
