I have had a lot of experience with ICD/Pacemakers from a patient standpoint. I am on my 3rd one and have had one almost 20 years now.

When I started Entresto and Carvididol my pulse rate went down into 30s. My EP raised my pacemaker rate slowly and slowly to see where the pacing corrected my irregular heart beats and PVCs improved. I now have it set at 70 bpm.

From my standpoint of a patient a very low pulse rate unless a athlete with powerful heart is not pumping enough blood to prevent dizzeness and fatigue. I have no idea if there are drugs to raise pulse rate most of time is to lower them.

But a pacemaker can be set at any rate to bring your heart rate up to where you don't have the dizzenes if that is the cause of your dizzeness. I want to pass on to you from a patient standpoint that geeting an ICD/Pacemaker these days is an outpatient procedure and usually go home the same day.

You will have some restrictions to make sure the leads seed properly but could provide a drastic life change if it is deemed one would remove your symptoms. I just trying to pass on that millions get ICD/Pacemakers these days and if can improve your life or help save it I would strongly consider it.

How is your BP? A low BP also can cause dizzeness and fatique.

I did a sleep study at Mayo but my study came back not a recommendation for C-Cap (spell?). I hope they find the cause and you get the appropriate treatment.
