Palpitations (a syndrome characterized by a subjective sensation of violent heart beating and frightful uneasiness) occur because the Heart lacks blood nourishment, resembling a fish without water; the mind feels terrified and trembling with palpitations, appearing as if one is about to be captured. If palpitations are triggered by overthinking, this indicates Blood deficiency.
