yes it can! in fact i will explain in a short detail my experience with heart related anxiety.
i had daily occurrences of dizziness. i had sore throats maybe twice a month! i generally felt achey/tired/breathless. i felt completely hopeless and thought i was really dying and it would be a matter of any day i would go. i then went on meds, and since then have dropped most of them symptoms.
I was diagnosed five years ago at the age of 51. I had symptoms for 3-4 years prior to that but did not know anything about Parkinson’s. I first noticed a slight twitch in my left hand, finger and thumb, which became pill rolling. We attended a lot of sports events and I would lose my balance in the moving crowd. I then started seeing a neurologist. I started falling a lot when losing my balance and had a hard time walking normal. I finally froze up in the doorway at church. I told my Neuro and he said that I had Parkinson’s. Started me on entacapone,levodopa, carbidopa, and pramipexole and I still didn’t feel or get better January 2017 my neurologist and I decided to go with natural treatment and was introduced to Green House Herbal Clinic natural Parkinson’s disease Herbal formula, i had a total decline of symptoms with this Parkinson’s Herbal formula treatment.

You might have an inner ear problem or Mineire's Ear. This can cause dizziness when the head tilts, and would also thus explain the nausea. Don't know if this is the case, but an extremely complete series of medical evaluations seems in order.
Anxiety can cause tremors, but this sounds like it could be more than that. Do you have any other symptoms, like dizziness or palpitations when you stand up? Do you get the tremors even when you're not especially anxious? If either of these are true, you may want to research dysautonomia, or autonomic nervous system dysfunction. It can cause episodes like this.
