I suggest a second opinion as well. You had an ablation done so I would get the report and take it to a second cardilogist and see what they think. 170 is pretty high. Did they at least prescribe you some meds to take when you are having a high rate. From what I understand there is some sort of bp med that can be taken to help slow the rate when it is happening but you need to discuss that with your doctor. As for the exercise can you do a stationary bike or eliptical which isn't that hard on the knees? If not maybe consider a bit of weight resistance which can elevate the heart rate. Well good luck. I hope you can get to the bottom of this. Passing out is indeed something to be taken seriously. Keep us posted on how you are doing.

You might think of getting another opinion from another cardiologist. Does your rate stay steady at 140 and for how long? Hours, minutes? It sounds like it might be an electrical problem like flutter. If you give more specific info, others may have had the same symptoms.
There are many people in your situation so do not feel like you are the only one dealing with this.

told to work out which out which with my knees not going to happen/ so going back next month and try to get something feasable. my BP drops very low which cause a chance to faint and fall.
a long time/ have been told it was in my head and don't worry/ till the BP drops so low that I can pass out they now look at it.
it can stay high for some time drop and for days just like a roller coaster up and down/ they told me do cardio for a 1/2 hour a day/ to do this I will need my knees replaced. So far that was their solution which is not going to happen/

I am sure your doc will explain things to you. You did not give us much info.
How long has this been going on? How long does your heart rate stay at these rates? What are you doing when it goes high?
The doc will probably prescribe drugs to help keep your rate down. I doubt if a pacemaker will be an option.
Good luck

I would think the Dr would tell you something. When is your follow up appointment? I hope you get your answers.
