Hi. I've just had my first PM change after 8.5 years, I am male and 73 years old, and would appreciate any comments. I have gone from a Sorin Reply DR to a Boston Scientific Proponent L211, which seems physically slightly larger. I have been a little spooked by some of the comments on the internet regarding the Boston Scientific I am now using, so any comments about their performance would be welcome. Hope some of the experts on here can give me some reassurance. Many thanks in advance, Roy.
