So took your advice and went back to my old hospital for a second opinion.
On my last box change the new hospital changed my settings to 50bpm instead of 60bpm as they had been for 23years also they turned off a damaged lead and didn't replace it saying I didn't need it.
Tec today wasn't happy with what they have done but says I am OK without the other lead but she is going to speak to her boss and come back to me.
My PM has now been set at 60bpm but since I got home 5hrs ago I can feel myself pacing all the time, I understand that it's gona kick in earlier but this didn't when it was last set at 60 so why now? It's not a nice feeling is there a answer to this
