Heart palpitations (due to vigorous physical activity, emotional stress, etc.)

Place the thumb of each hand over the nails of the ring and little fingers on the same hand. Both hands simultaneously. (It resembles somewhat the “Victory” finger sign).  Incidentally, that is the self-help for the SEL26 harmonizing sequence. The friend who taught me this finger placement ran a marathon while holding her thumbs over the ring and little fingers.
