Multicenter StudyValidation of a verbal rating scale for breathlessness amongst patients referred for cardiac stress tests.
Acute shortness of breath (SOB) is a common symptom and a potentially significant marker of cardiorespiratory disease. The subjective and unmeasurable nature of breathlessness can make its clinical evaluation difficult. This study aimed to investigate the convergent validity of a verbal 0-10 rating scale for SOB. ⋯ A verbal numerical rating scale is a valid measure of breathlessness and may provide useful insight into a prognostically significant symptom.
