Pacemaker to ICD upgrade
I am a 42 year old male with a dual chamber Medtronic pacemaker for heart block that was fitted 6 years ago. I have been told by my cardiologst that i may have to have my Pacemaker upgraded to an ICD in the near future. He explained that the procedure is dangerours and not something that they will do unless necessary due to the changing and removeal of the leads.
Can anyone shed any light on this or has anyone had any expereince of this being done? And what are the differrence in having an ICD compared to a pacemaker? Are there any differences between them that I should be aware of? I am very active and doing regular intense exercise and keeping fit is a big part of life.
Thanks in advance for any advice.
