Hi I have a pacemaker and have been having a
Real tired when I walk.
Ranaway pacemaker, seek medical attention soon.
Hello dear, welcome to Ask a doctor service.
I read your query and here is my advice.
I think your problem is a ranaway pacemaker. Your tachycardia is above the upper limit that the pacemaker generator is supposed to discharge.
You should seek medical attention soon.
Magnet application may be tried or maybe you need to remove pacemaker.
Hope I have answered the question.
Let me know if I can assist you further.
