Is it possible that the 22 year life span is because people usually get them implanted at a later stage in their life and so they were probably the majority of the I think that the survival rate would be the same as a person without a pacemaker.
I don't know where was the lady read that 22 years from? She can't post website in that forum. I google and this one turns up. My English is not good so I only can understand one quarter of the content in this document. Could some one read and tell me? Thanks.
Reading the paper abstract it deals with a study looking at a whole range of people who have had a pacemaker fitted for a wide range of reasons. In addition, the date of the implant of the pacemaker ranged over several decades (so some of the pacemakers were the earlier types). It does not say that the average lifespan was 22 years after implant, what it does say is that if you have structural heart problems, then you are less likely to live as long as someone without a pacemaker. However if you do not have structural heart problems then there is no difference in life expectancy compared to those who do not have a pacemaker.
The issue then appears to be whether you have structural heart disease as to whether your lifespan is likely to be affected, and because the paper does not look at a comparison between those with structural heart diesease but no pacemaker and those with structural heart disease and a pacemaker, they cannot be sure if the pacemaker is responsible for the decline in life expectancy or whether the underlying heart problems are the cause.
The paper itself is from 1999 and therefore does not reflect current practice or equipment and because it covers 30 years of patients it dates back to procedures done in the late 1960's. You need to be careful when you read these papers on the internet to make sure you consider all the elements of the research. Even just the abstract shown here qualifies the work and provides the context for the results reported and you must consider that and not frighten yourself. Hope that helps!
