Suggestion takes many forms, and the solemn shake of the specialist's head is among the less forgivable; the man ought to be aware enough of his responsibilities to avoid such theatrical gestures. However, it is the patient himself who often provides the negative suggestion. A combination of near-total ignorance and unrestrained imagination can intensify a slight misfunction beyond belief. A high proportion of those who consult heart specialists are driven to do so by their own exaggeration of symptoms: An occasional sensation of a flutter in the heart, or a missed beat can, through anxiety and unfounded fear, produce truly serious tensions and resultant heart murmurs. These, in turn, may easily mislead the near-sighted specialist into grave pronouncements.
Such unnecessarily tragic series of events can develop from awareness of abnormality in any vital function, but are infinitely more intense where the heart is involved. A comparatively slight and passing distress, brought about by excitement, lack of sleep or an unusually heavy meal, makes the individual heart-conscious for the first time. His response, and the advice he receives, may determine whether the outcome be complete and rapid recovery or a life of chronic invalidism. The undermining of self-confidence is the first step in a degenerative process, which is hastened and intensified by the administration of drugs and devitalizing treatment.
