This is Sandy. When she was 6 months old she was diagnosed with severe heart arythmia and her parents were told she should avoid stress, excitement, and physical exertion. I get the sense this was early 1900s. She was unable to play outside and this made her very sad (she actually made me cry). She was 9 when she passed away from an attack. She was running but i am not sure why. Very strong intense energy and may cause feeling if tightness or pressure around heart.
