NCT06672861

Brief Summary

Main aim will be to compare in patients with cardiac dysautonomia, newly developed disease specific questionnaire to established generalized SF-36 and EQ-5d questionnaires, as there are no disease specific questionnaires for comparison. These novel and established questionnaires will then be compared among groups who have relatively stable disease or stable symptoms with patients who will be expected to have a change in symptoms and QoL.

Outcome Measures

Primary Outcomes (1)

  • To develop and validate KCDysQ as a quality of life and symptom severity assessment tool

    The primary objective of this study will be to develop and validate KCDysQ as a quality of life and symptom severity assessment tool that can be widely applied to patients with symptoms of cardiac dysautonomia, and doing so by proving the questionnaire's reliability, validity, responsiveness, and acceptability.

    3 Months
