What I am really trying to find answers to is, while I am in a restful state, I get very strong palpitations, I then feel like the blood has rushed out of my body, and I feel cold and weak, and afterwards my
heart feels sore, and I feel very unwell
for a long period of time. I also get these strong palpitations after strenuous work, such as digging in the garden. So whether I am resting or exerting myself I get the palpitations.
