Changes in quality of life measured by the physical component summary (PCS) measure of the Short Form 36 Health Survey Questionnaire (SF-36). |
Changes in quality of life measured by the physical component summary (PCS) measure of the Short Form 36 Health Survey Questionnaire (SF-36) from baseline to 12 weeks. |

Changes atrial fibrillation specific quality of life measured by the Atrial Fibrillation Effect on Quality of Life Questionnaire (AFEQT). |
Changes atrial fibrillation specific quality of life measured by the Atrial Fibrillation Effect on Quality of Life Questionnaire (AFEQT). The AFEQT assesses 4 domains: symptoms, activities, treatment concern, treatment satisfaction, and a summary score that includes the first 3 domains. Patients will assess the impact of AF on their health status during the previous 4 weeks. Responses are presented as a 7-point Likert scale. Raw scores within each domain are transformed to a 0 (most severe symptoms) to 100 scale (no limitations or disability). The AFEQT is valid, reliable and sensitive to clinical change in patients with AF undergoing different therapeutic interventions. |

Changes atrial fibrillation specific quality of life measured by the University of Toronto Atrial Fibrillation Severity Scale (AFSS). |
Changes atrial fibrillation specific quality of life measured by the University of Toronto Atrial Fibrillation Severity Scale (AFSS) from baseline to 12 weeks. The AFSS is a disease-specific quality of life measure used to capture subjective and objective ratings of disease burden in patients with atrial fibrillation. It assesses atrial fibrillation burden (score 1-30; higher scores indicate higher burden); Global Well Being (a visual analogue scale ranging from 1-10, indicating a patient reports as having a worst possible life [0] to the best possible life[10]); AF symptom score (score of 0-35; higher scores indicate more bothered by AF symptoms); and health care utilization (score of 0-21; higher scores indicate greater health care utilization). |

Changes in symptom burden measured by the Canadian Cardiovascular Society Severity of Atrial Fibrillation Scale. |
Changes in symptom burden measured by the Canadian Cardiovascular Society Severity of Atrial Fibrillation Scale from baseline to 12 weeks.The CCS-SAF is a simple, concise, symptom-based severity scale to assess patient status. CCS-SAF scores range from 0 to 4, with highest values denoting severe impact of symptoms on quality of life and activities of daily living. The CCS-SAF has been validated in patients with atrial fibrillation. |

Changes in quality of life measured by the mental component summary (MCS) measure of the Short Form 36 Health Survey Questionnaire (SF-36). |
Changes in quality of life measured by the mental component summary (MCS) measure of the Short Form 36 Health Survey Questionnaire (SF-36) from baseline to 12 weeks. The SF-36 is a widely used and thoroughly validated, standardized, generic health survey with 36 questions. It yields an 8-scale (physical functioning; role-physical; bodily pain; general health; vitality; social functioning; role-emotional; and, mental health) profile of functional health and well-being scores as well as psychometrically-based physical (PCS) and mental (MCS) component summary scores. |
