Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Various symptoms can occur during an AF episode, including dizziness, heart palpitations, chest pain, and fatigue. Standard treatment of AF include rhythm- and/or rate-control medications, electrical cardioversion, and in some cases catheter ablation. The treatment focuses on re-ducing symptoms and improving quality of life (QoL).
AF episodes can have negative impact on patient's physical and mental health, as well as so-cial life. Individuals with AF often report poorer QoL, and experience symptoms of stress, depression, and anxiety. Guidelines recommend self-care programs that reduce symptoms and enhance QoL and recommends regularly physical activity to improve overall cardiovascular health. Yoga has been shown to improve health-related quality of life (HRQoL), reduce blood pressure and heart rate, and reduce AF episodes in small studies in-cluding individuals with paroxysmal AF. MediYoga originates from Kundalini Yoga, and is based on deep breathing, combined with slow movements, meditation, and relaxation exercises. MediYoga is designed so that many of the exercises can be performed while seated.
The increasing proportion of older individuals living with AF, demands new ways of organizing and implement rehabilitation for patients. Tele-health, defined as the delivery of health-related services through digital communication technologies is eligible to provide yoga classes at home. Online interventions might increase the likelihood that participants complete the program, as it can be done in their own surroundings without required transportation. Remote recruitment has increasing potential, as it enhances the possibility to include participants from rural districts, who might not participate in onsite rehabilitation, due to the long distance to a rehabilitation center.
To our knowledge, this study is the first study to investigate the effect of an online yoga intervention for patients with symptomatic paroxysmal AF, using a complete online recruitment and implementation strategy.
This study is designed as a randomized controlled digital trial, and will be conducted as an international study with recruitment in both Denmark and Sweden. This study will be conducted as a parallel study with the Swedish study. No data will be transferred. The analyzes will be done separately but published in the same publication with comparisons between countries.
The study is designed as a three arm, randomized superiority trial. Participants will be randomly assigned to one of two groups (1:1) (I) control group including treatment as usual (TAU) alone, or (II) intervention group, in which participants will be allocated to one of two groups, based on their personal preferences; (IIa) performing yoga three times a week for 20 min or (IIb) performing yoga once a week for 60 minutes, for at total of 12 weeks, in addition to TAU
To explore how participants experience being a part of the study, 12-15 patients from each intervention group will be interviewed using qualitative methods. A semi-structured interview guide will be developed through the intervention period, as interesting themes arises. Questions will be formulated to both capture patients experience of the recruitment process and being a part of a study using health technology and remote participation, as well as how the patients experience carrying out the intervention using an app and being in their home. Data will be analyzed using thematic analysis.
All data are self-reported by participants; therefore, access to patient records is not required.
The primary outcome is the disease-specific questionnaire, ASTA. The validated form is divided into three parts: evaluation of the most recent episode of arrythmia and current medication assessment of symptom burden, including a 9-point symptom scale (ASTA symp-tom scale) with a 4-point response scale, and assessment of the HRQoL using a 13-point scale (ASTA scale) with the same 4-point response scale as the symptom scale. The ASTA scale is further divided into a physical and a mental subscale. Scores range from 0 to 100, with higher scores reflecting a higher symptom burden and a worse impact on HRQoL due to arrythmia.
The SF-36 is a standardized, validated, and reliable general HRQoL questionnaire containing 36 items.The items are divided into eight domains and two component summary scales reflecting physical and mental health re-spectively. The two summary scales are analysed on a 0-100 scale, where 100 represents the best possible HRQoL.
HADS is a reliable and validated instrument for screening for clinically relevant symptoms of anxiety and depression in patients. The scale consists of 14 items assessing how patients felt during the previous week. Patients must answer every question in a 4-point Likert scale from 0 to 3. Seven of the items assess the level of depression, and the remaining seven the level of anxiety. Scores are summarized separately for anxiety and depression, resulting in two scores with a range of 0-21. Higher scores indicate more symptoms of anxiety and depression.
In addition to the self-administrated questionnaires, Participants in both the intervention and control groups will be asked to measure their blood pressure and heart rate using a device provided by the research team. They will receive a detailed guide on how to perform these measurements at home, in accordance with the European Guidelines for the Management of Elevated Blood Pressure and Hypertension. Participants will be instructed to take their measurements in the morning, prior to breakfast and any medication intake. Additionally, they will be asked to empty their bladder, refrain from smoking for at least 30 minutes beforehand, and rest for 1-5 minutes before beginning. Blood pressure and heart rate should be measured three times, with 1-2 minutes between each reading. Participants will complete questionnaires and perform blood pressure and heart rate measurements at baseline, 3 and 6 months follow-up.
Sociodemographic characteristics including age, sex, occupational status, educational level, marital status, medication, and comorbidities will be collected via self-report at baseline.
Statistical Analysis Comparisons between the intervention and control groups will be made using Chi-square tests for proportions and repeated measures ANOVA for analyzing questionnaires, blood pressure, and heart rate. Student's t-test will be used for within-group anal-yses. Analysis of covariance (ANCOVA) will be used if a statistically significant relationship is shown between groups regarding demographic data. Drop-out rate will be registered in a flowchart and both per protocol and intent-to-treat analyses will be performed. The level of significance is set at p\<0.05. The analysis will be performed by a blinded statistician.
If the intervention proves effective, the findings could contribute to a scalable, evidence-based model for remote AF rehabilitation, supporting the broader movement toward digital and patient-centered care in cardiology.

Participants in the intervention group may choose whether they prefer to practice yoga for 20 minutes three times per week, or for 60 minutes once per week. The yoga sessions are delivered via a smartphone application, guiding participants through the sessions with both video and audio. In addition, participants are required to complete three questionnaires and measure blood pressure and heart rate at baseline, and at 3 and 6 months of follow-up.
