Your aunt is full of it. I'm 26, have had a pacemaker for 4 years now, and it has dramatically improved my quality of life. Pacemakers are extremely advanced, actually like mini computers; that records all kinds of data and only pace the heart when absolutely necessary. Pacemakers have long battery life, and usually only need to be replaced every 6-12 years. The surgery for implantation
is minimal, and in most cases can be done on an outpatient basis. There are so many people that are leading dramatically better lives today due to the advancements in pacemaker and ICD technology. Many patients feel an improvement immediately after the procedure because the effect is usually immediate. I could go on and on, you might want to check out some of the websites below. Good luck, and rest assured your grandmother will be fine after a pacemaker implant. Feel free to contact me privately with any ?'s.
