What are the heart symptoms that FA patients experience?

The heart symptoms may have irregular heart rhythms, which they can feel as palpitations, as the heart beats faster or is irregular. It’s not really painful, but it can be uncomfortable and alarming. They may have shortness of breath and difficulty breathing when lying down, so they may feel the need to be propped up when they’re in bed. They may have swelling of their hands and feet, primarily their feet, as the circulation becomes sluggish.
