Does anyone else get a feeling of heart/chest and body weakness as a symptom of anxiety and psychosomatic fatigue?

I started to experience this and since I can't find much on this feeling, my brain is trying to convince me a bit that it's something else, although I had my heart tested a bit and it occurs mainly when I'm consciously or subconsciously anxious.

It's like my heart was really light, almost floaty and weak. Maybe it could be described as an empty feeling as well.
