It probably has nothing to do with our kidneys. I do not see a connection. Pauses at night are usually not a indication for a pacemaker. The key is if you are having symptoms during the day when you are awake. If in doubt, get a second opinion. If you are fatigued or run down, heart rates that low can sometimes cause subtle symptoms that you don't know you had until after you get the pacemaker. I hope this helps.
Thanks it does help. I did get a second opinion and he was not as strong about the pacemaker but felt it was the way to go. He said I could wait till I did pass out and maybe hurt myself or someone else. I am light headed during the day but have not passed out. They said that because I am light headed during the day and that my pulse is so low at night it is most certain sick sinus syndrome and the only way to deal with it is a pacemaker. Thanks for you answer.
