Can I Get an LVAD to help me? I'm from the United Kingdom, Northern Ireland

I have a high heart rate (~115 bpm at rest, and when I do anything over walking 20 metres per day my heart rate goes up and takes some days to return back down to ~115 bpm again), due to this my life is severely limited in what I can do, though I am only 22 years old. I have tried researching various causes of what I am experiencing and can only conclude that I have a weakened left ventricle. Does what I am describing sound like I could get an LVAD to help with it?
