Rick, the EF you quoted indicates that you have taken some damage to your heart muscle, but not as much as you might have. What that means, is that you have to re-build your strength - like any muscle injury.
I assume you have been put onto a cardiac rehabilitation programme? If not discuss with your docs.
And to counteract your “creeped out “ feeling (better already - before you were “grossed out”), remember that you did not feel anything going on inside you while they were placing the stent - it was all on the skin. Next time, ask for some local anaesthetic at the IV site, or get them to use one of the modern infrared or laser vein finders.
Now look at the next step - do you need a pacemaker? If so, do you want to go on long walks, or not?
Would you have driven your fancy car with a blocked fuel filter and a dodgy spark plug?
And remember to reduce the load on your heart - don’t lift stuff you can get somebody else to lift, and if you are carrying too much weight, get rid of some of it. And I trust you are a non-smoker?
I’ve never smoked a day in my life ,but I second hand smoked 2 packs a day in the 60’s and 70’s .
Next option may be cutting the nerves that control the heart, and installing a pace maker.
I’m unemployed in another month , so I may just live with what I’ve got.
The low oxygen is because of the rapid heart beat (I think )
My resting heart rate is still 96 bpm.
I was walking part way to work yesterday,when my left arm went completely numb . I could move it but had little feeling in it.
I lifted my arm and touched my watch and it magically went back to normal. The darnedest thing .
I have an appointment with my GP on Friday and I’ll mention it . Maybe the dye they put in you reacts for a while . This was the 6th day though
